Hi all ~ Ive already decided what we'll be doing. Infact, I'm super excited about it... I used to make these each year for my kids (when they were smaller - and it was cool to have Mom make things for you) to match their costumes... We'll be getting those plain canvas bags from Oriental Trading Co. (gee, I love that place!) and they'll be decorating them with Fabric Pens ( this is where Im kinda stuck ) Anyone use the Crayola Fabric Pens - on canvas, whom could let me know how these will work? Would I be better off with just Permanent Markers, in colors?
