I did one for the school auctions years ago - well I put it together anyway... the children made the blocks. I went into the 2 special education classes and provided each of the 12 children with a block of colorful batik fabric (there were 4 different fabrics). They cut out shapes & images from contact paper, stuck them on their blocks, painted black on them, let them dry and then the kids removed the contact paper to reveal their designs. I gently washed the blocks & then put them together with sashes of the batiks and a black outer border. I just did stitch in the ditch as I don't really quilt & this allowed their blocks to be the stars of the quilt.
