What do you do if you don't know if your fabric is 100% cotton? Also, I have a lot of strips from my stash but I usually don't wash my fabric but by my understanding they need to be washed & 100% cotton is that right??? Help! I haven't even started on mine so I guess I'll be doing some marathon sewing don't you think????

Here's a link where they tell you how to test to see if your fabric is 100% cotton or not.

Can't help with the other part of your question :)

You can wash the strips by hand :wink:

Thanks for the infor. Dumb, dumb here didn't think of washing them by hand! LOL!

Not dumb--I didn't think of it either and I don't consider myself dumb by a long shot! :-)
