"Everyone should have a small collection of purple prints, tonals, or solids.  You will likely want more prints than solids if you want to try the exercise with bias tape.
I recommend 5 prints but more might be more fun - scrap pieces between 6" and 10" would work perfectly.  If everyone brings a duplicate piece of one or two of their prints, then we can do a trade to increase the possibilities.  You could end up with 7 scraps to play with.
We will be investigating purple and its complementary, analogous, and triadic colours.
In the bias tape exercise you will need a piece of background fabric - I will be using a 20" square so that I can use the exercise later for a small table topper or pillow but you can use whatever size you want.  Don't go too small or it will be more challenging for you.
For your background fabric, choose something like a solid or tonal or maybe a very low value print.  Some suggested colours are white or gray but if you want to be a little more adventurous, purple's complimentary colour is yellow-green and its triadic colours are orange-yellow and aqua-green.  You could also consider a very low value such as a very pale pastel of any of its analogous colours from blue-violet around the colour wheel to blue-red.
You don't need the bias tape - I will have a selection of 3 different colours.
You will also need scissors, pins, an erasable marker such as that gel pen that irons out or a chalk pencil.  The water erasable pen will not work as well for this exercise as you may be ironing your piece before you rinse it.  A glue stick would be helpful but if you don't have one, I have one you may share.
If you have a piece of very fine sandpaper, bring that as it will make drawing on fabric a lot easier.  I have a 12" square that works great. and everyone is welcome to use it - I know this sounds like an odd piece of equipment.
And, of course, your sewing machine."

For the improv supplies:

• Scraps of random purple fabric and for the strips and chevron- have these fabrics cut in strips at least 2” longer than the block you are making.  EX: 8 1/2” block cut 10-11” fabrics.
• Sewing supplies and a few strips of foundation fabric that can be cheap scrap fabric in a light colour so it doesn’t show through.
