We've been using fabric crayons for projects forever, it never gets old! Our favorite thing to make with them is pillows. The only "important" thing to remember is because you draw on paper & then transfer to fabric your image will be reversed which is important if your doing any letters or numbers. I obviously forgot this rule despite my many years of using them, the date in the corner is backwards!
The other important thing with these is its best to use a poly / cotton blend.
Dye Sticks Crayons
I LOVE these even more than traditional fabric crayons for several reasons.
You draw right on the fabric, you don't have to worry about mirror image &
the colors are nice & bright.
