You guys probably know but it's news to me! I was making my sister a baby blanket (she's due to pop any time now!) and had the stencil I wanted to use for the quilt pattern. In the past I've used the markers from Joann's or chalk but I didn't have any. Besides that the markers and pencils aren't really ideal imo, and chalk... well, it's chalk.

So I'm looking around wondering what I can use without running to the fabric store and I come across my kid's old Crayola washable markers. Big pack, multi-colored and nice tip. I try it and keep my fingers crossed hoping I'm not ruining the quilt.

I finish up and cross my fingers as I put it in the wash and it all came out! It was perfect! I can't believe I hadn't heard of this before or thought of it myself! What do you all use?
