I am so sorry this happened to you and I must share with you all my experience. I am totally new to quilting so when I made a jelly roll quilt with the Bali Pops - I think it was called Bars of Gold - I thought it was my fault when everything came out "wavy" even though I was extremely careful with pressing and cutting. I did notice throughout the whole process that the strips were not evenly cut but once again figured that because I was new, I didn't know what I was talking about. I also noticed that some of the material felt "thinner" than other pieces if that makes any sense. After reading all of your comments, I now know it wasn't me. I did not like this product and planned on never buying it again.
