Wasn’t thinking specifically about art or bookmaking or math, but it all seeps in.
Had these stretcher frames in storage, pulled them out, hinged them together in the same way as if I were making a Jacob’s Ladder. Small pieces first,
Long pieces next. Hinges made of Tyvek. Husband lent me his power staple gun.
Next I needed to glue some pieces together. I’m planning something that’s kind of large, but need to start with the small pieces.
Assembling on my dining room table. Husband not too happy about this, but he was accepting.
After the frames were assembled I took the frames outside. The next part, adding small nails to stabilize the corners, was done by my husband. It’s a good sign when I like the visuals of an object while it’s still in process. I liked the way this was evolving.
This is a screen for my son’s apartment. I want it to be sturdy, large, lightweight and luminous. I am using drafting film for the openings. Decided to make wavy edges.
For five screens, I made 10 curtains of drafting film. Attached the pieces with double sided tape.
Attached the curtains of drafting film into the stretchers with double sided tape. I think it will hold, but if not, tacks can be added later.
Here it is, done, a humongous Jacob’s Ladder, which merely means the panels can fold in either direction.
I hadn’t made anything this large in a long time. It’s now out of my house and at my son’s place.
What I realize about making this is that it really is a response to what I need to be doing now, which is building something new.
This pandemic times are changing things for me.
So I started with something small, a few little stretcher frames and an idea.
Ended up with something large and satisfying.
Change is in the air.
Hadn’t meant for this screen to be a metaphor, but it seems fitting. These pandemic times, and this time of civic changes, requires building something new, starting with disparate pieces, putting things together, making something good.
In late May I had been looking at a book called Painted Prayers, by Stephen P. Huyler, which showed the geometric drawings that were made daily by women, as a blessing for their home and their communities. After George Floyd’s murder and the protests that followed and spread, I made a geometric drawing with the intention of leaving it somewhere in the community, as a blessing, a wish for a way to move forward in a good way.
When I brought my little drawing into town I saw that someone had tacked a #BLM kind of sign on the community bulletin board. I pinned my drawing below it, feeling like it would honor and protect the sign. It occured to me that my drawing would disappear from the board by the next day. No matter. I went home and made another one the next day.
Both the sign and my drawing were still there when I brought in the second drawing. I went home and made another, then another the next day.
The sign and the drawings remained.
One day that I went into town to post my drawing, there was a gathering for Black LIves Matter on the only intersection of this small town. I heard that about 150 people had taken part in it.
One day I missed making a drawing for the board, so the next day I made two.
As the drawings were left untouched day after day, I was committed to surrounding the sign with my blessings.
For some reason, the last one was the hardest to make. I did three version before I got something that felt right.
Then the frame was finished.
Such a small gesture, but I think every gesture is worth doing.
One last thing, I left blanks of what I drew for people to take.
My friend Bonnie heard from her friend in Minneapolis. There was a ray of light in her description of how, as the chaos has swept the city, that neighbors are showing up with food, supplies and compassion to help each other.
Then Bonnie read me this line from her friend’s note “…and the artists have shown up. There are a couple of new murals on the sides of building. Everything is boarded up but artists have come and painted beautiful things.”
Today, I am hoping you will make something beautiful.
This is the one-stop post for making a linear pattern with a repeating tiles, otherwise known as Frieze Group Symmetry.
I recently wrote 10 posts about this kind of pattern making, going over nuances and details one at a time. This post is not that. It’s aim is to demonstrate Frieze Group symmetry in a way that will make the basics of this symmetries really accessible. I hope you will play along. Actually creating the symmetries is the easiest way to learn them. IT IS SO WORTH LEARNING THIS! Playing with these symmetrie expand design possibilities beyond what you can imagine.
There are many different symmetry groups. Frieze group symmetry is a great place to start because they follow one simple rule: repeated tiles can only move linearly, which means they can slide, thus moving in a linear direction, or they can have 180 degree transformation. There are only 7 possible ways to make a linear symmetry. Considering we generally only think of symmetry as a mirror reflection, this may seem more than you expect.
To play along, you need four squares that
have a design on the back that is a reflection of what’s on the front, and
which the design on the square is not symmetrical.
The easiest way to do this is to just stack four square post-it notes and cut an asymmetrical design on them while they are still stuck together.
If you want something a bit more snazzy and have access to a printer, print out either the color or black and white version of my symmetry tiles.
You’ll cut out four of these rectangles, which are domino proportioned, then fold them in half to make squares. Glue insides together, and you have your own set of paper symmetry tiles to use.
I will be adding to this post for seven days, so we’ll do just one symmetry a day.
If you take your tile keep repeating it exactly how it is, this is called translation and it looks like this:
There you have it! Your first symmetry group.
To be continued on this page tomorrow.
All frieze symmetries have the translation action embedded in them. Here, with Glide Reflection, a copy of the first tile slides over (translation) then it reflects horizontally, as if there is a horizontal bar that it is flipping over. This shows you the back of the tile, which is why the tiles I’ve provided above in my pdfs, give you the image as if it goes right through the paper.
If you are using your own cut squares, be sure that the design you’ve cut makes it so there are no lines of horizontal or vertical symmetry!
If you are confused about this, or want to know more about this particular symmetry, take a look at my glide reflection post.
to be continued tomorrow….
I think of this frieze group as the paper doll frieze group. Remember cutting out paper dolls from a piece of paper folded like an accordion, and the result would be linked paper dolls? If you don’t know what I’m talking about, do a google search for accordion paper dolls!
The Vertical Reflection frieze group slides a tile over, then reflects across the right side of the tile. Repeat and repeat again.
Some of these symmetries seem easier to wrap my brain around than others. Seems to me that this fourth symmetry, rotation, is one of the easier ones. Remembering that all the symmetries start with translation, which means sliding a copy of the first tile over, this one then rotates 180 degree, going from right side up to upside down.
This frieze group combines the first three groups into one. Not sure about glide reflection? Better get clear on it!
The action here is to slide over the first tile then reflect it across a vertical axis (mirror reflection).
Now here’s something that’s new to this frieze group: take a copy of the two tiles, slide them over, then reflected them across a horizontal axis. This is glide reflection.
This is the first (of two) of the frieze groups where you need a minimum of four tiles to achieve the symmetry of this specific one of the group.
So close to the end of Frieze Group symmetry , here’s one that super easy to understand, Notice that there’s a new thing that happens here.
The action is to take a copy of the first tile and rotate it across a horizontal axis, the same kind of reflection that a tree does with the water at it’s base. Next, slide (translate) both these tiles to continue the pattern.
What’s new is that this is the first of these symmetries that require the design to become wider before it becomes longer. In a sense, it happens on double line.
If you understand what’s going on in all the other frieze groups, this one will be immediately understandable. If your understanding is still a bit sketchy, you’ll likely need a bit more time to sort it out.
LIke the one from Day 6, this frieze symmetry requires the pattern to grown in wider (or taller, depending on your perspective) before it grows longer.
Horizontally reflect a copy of the first tile. This means reflect the tile the way a tree would reflect into water. Next, reflect both tiles over a vertical line, like a mirror reflection. This is the unit of four repeats linearly.
