I've made crazy quilt jackets and vests using cottons only. on the pillows, I've mixed my fabs. I made a cute pillow out of my sons jeans and shirts when he was a baby, came out really cute. my jackets and vests were purely cotton, then embellished with cotton emb floss and beads of al types. on my black white and red jacket, I did use silver lame, backed with a fusible interfacing, to make it the same wt. as the rest of the cottons.
