Overdyeing - a kids' project

One of the "jobs" I have these days is being a substitute teacher. For now, I limit my subbing to the school where my own children attend. Since my oldest has gone through almost all of the grades there, I am quite familiar with all of the routines and curriculums. That helps to eliminate some of the stress a sub goes through when faced with a classroom of children eager to convince you "Mrs. X really does let us work together on math worksheets."

Last week I subbed in a 3rd grade class. This was a pre-arranged two day assignment. I love multi-day assignments because it allows me to plan ahead a fiber project for the kids. This time the kids overdyed light brown wool with food coloring. Educationally, it was a science experiment, in case the principal came in wanting to know how food coloring and wool were related to the students' instructional time. The presentation only took about 10 minutes. Putting fiber into their cup took about 20 minutes.

First, we talked about different foods that can cause stains. Putting this in the context of "has your mother ever gotten upset that you got strawberries/hot chocolate/juice/ketchup/mustard/etc... on your clothes?" we talked about natural dyes (strawberries, chocolate, mustard), fiber types (cotton, wool, synthetic) and the process of staining, aka dyeing.

Next, each student was given a strip of light brown wool roving about 12 inches in length. We used Wilton's gel cake decorating colors, which sadly I've recently learned is not light-fast but it served its purpose for this experiment. Each student picked a color. In cases where more than one student picked a color, we made an effort to make different strength solutions to get light and dark shades. Note: Ahead of time I made a list of possible colors on the board limiting the number of students per color lest we have all the boys pick blue and all the girls pick violet.

We put water, a glug of white vinegar, and some of the Wilton's gel into cups. The kids put their roving into the cup, use a spoon to submerge it (we didn't pre-wet the fiber) and place the cup in the sunny windowsill. My intention was to dye this using a modified "sun tea" method. Unfortunately, the sun wasn't cooperating. I knew by the end of the day that I had to speed up the process. I made use of the microwave in the teacher's lounge after school. Three of the cups were left un-finished on purpose so the kids could see the difference.

On the second day, I showed the kids the un-finished cups with the rovings. The fiber did have some color change but the liquid was also still colored. Then I showed them the exhausted cups. They were amazed to see the colorful fiber but even MORE amazed at the clear liquid. "Where did all the color go?", they all exclaimed! I used the two liquid examples to emphasize the need for heat as an integral part of this particular dyeing process recipe.

We also looked at some of the violet and black rovings up close. These food coloring colors tend to split - meaning they'll separate into their main colors and strike fiber unevenly resulting in splotchy dyeing. Some fiber artists call that a "feature" and rely on it for effect. I used this feature to remind them how colors are made (violet = red + blue, green = yellow + blue, black = many colors) and explained that in this case the colors didn't stay mixed once in the water and after separating, the fiber dyed with the separate colors. In our experiments, one of the violets was pink streaked with blue and one of the blacks was green.


The colors we used were:
Christmas Red
Red, Red
Leaf Green
Kelly Green
Yellow
Orange
Violet
Royal Blue
Brown
Black
The strip of light brown roving at the top just above the purple-violet and to the left of the red is a strip of the original colored roving.


Things to do differently next time:
1. Use glass jars instead of plastic cups. It lets the kids see the contents from the side instead of having to stand over the cup to look inside.
2. Pick less colors. Period. I let each student "own" a color but this meant that as I was working with the one student, the rest sat there unoccupied. This particular class is wonderful so there weren't any problems but I wouldn't count on that being the case in the future. From now on, I would work in groups (this was a class of 19 so perhaps groups of 5) and give the others a worksheet to occupy them until it was their turn.

What will become of the rovings? Check back in a few weeks because I've volunteered (i.e. no pay) to go back to the class in early June to finish up.

It's the little things....

that can make a chore so much easier. I've done toenail trimming before and it is such a big job for me that I could only do a handful of animals before being tired and plain worn out. I couldn't understand how Wayne (of Foothill, where we agist) could grab a foot, snip, snip, snip, move on to the next foot and be done with all four in no time flat.

A few weeks ago I was at 101 Alpacas for their shearing day. I went so that I could see how others do it and pick up on any tips for my own use. Well..... Vicki was using this tool that looked very much like a gardener's pruning shear to trim up toenails lickety-split! As I watched, I didn't see her doing anything particularly different from my method. She's considerable smaller than I am so I was pretty sure strength wasn't a factor. It had to be the tool. She said I could get a pair through Useful Items for around $20. I figured if they worked that well for her, it was worth it to me to get my own pair. And if they didn't work any better than the nippers Wayne uses, oh well, at least it's a write-off. I ordered myself a pair and they arrived Tuesday.

So today I went down to Foothill Llama and Alpaca Ranch with my new toenail clippers in hand. Wayne and I rounded up the boys where my two hang out. We caught BB who wasn't too keen on being restrained, let alone having his feet touched. I was a little worried about poking myself or the animal with the ends of the clippers so I proceeded very carefully. Wayne held BB's head and I "wrangled" a foot. Well, I must say I was VERY impressed with my new instrument. It cuts through black toenails like a hot knife through butter! Wayne and I trimmed up 5 boys in about 30 minutes (and weighed a few while we had halters on) and when we were done, I wasn't tired. More significantly, my back wasn't killing me from bending over. And of course the boys seemed to be walking a little prouder now with their newly manicured toes!

The tool is made in Japan by a company named Saboten. The blades are teflon coated and the handles are orange. I've been told there's a green-handled version out there that has stainless steel blades but the person said they bought those in Canada. Those are easier to re-sharpen. For now, I'm simply in love with my bright orange snips!

The next tool on my list: the Tooth-A-Matic tooth trimmer put out by The AlpacaRosa.
