The only reason I kept the diary is to see how long it takes me to make a quilt because I work full time and only have time to sew on the weekends and sometimes at night. I didn't keep track of the cost of the fabric and batting, but I think the entire quilt might have cost me about $135.00. I only started quilting last year and I only make quilts for myself and for my family. I don't really plan to ever sell anything I make.
