An Art + Quilt study group in our guild is having a swap when Lyric Kinard, quilt teacher of the year for 2011 by the International Association of Professional Quilters, presents at our quilt show in Cedar Rapids, IA, in September.
I had never heard of ATC before and wasn't sure I wanted to participate. I don't know what I'll do with them, but after making mine, I don't want to give them away. : )
They are just very little quilts that get swapped or sold. I think some people keep them in plastic sleeves or sheets with pockets.
I use muslin (Jo-Ann's Legacy Studio). I draw with a pencil and color. I make more than one on a piece of fabric. I layer with Peltex and backing, free motion stitch, cut apart, and then stitch around the edges.
