I don't have much wasted fabric at all, not enough for me to save to use. I cut the fabric to fit the die, not the mat. I don't understand why it was taking a large amount of time to cut the fabric, it takes a few minutes to cut hundreds of strips or squares using the quilt shop model. The quilt shop in my area is cutting end of bolts into charm squares and jelly rolls and they are a top selling item. The shop owner told me she does not have remnants to sell any more, it is all cut into charms and selling at retail prices. She told me about cutting the fabric to fit the die not the mat so no waste. Also old cutting mats can be used for the die mat, just cut to fit. The shop does not cut kits for sale but a customer who buys fabric at the shop can use the machine to cut the fabric. I have the Go!. The portable one. It is fantastic for me as I was having shoulder and hand problems after using a rotary cutter. Having perfectly cut fabric pieces of my choice in seconds is a joy.
