I have an off and on again quilt that I have been working on for some time. I know I'm not a perfect cutter, even thought all the seams line up the block wont lay flat!!! I am working with 4 inch square, into a 9 patch, then re-cutting them to something like a mosic, everyone knows it. I first cut the squares when I was making other quilts and had scraps left over. I put them all in the same area so I would know when to start working on it. That was this past weekend, I sewed several "squares" that were cut with one ruler together, and to my supprize it was wonky? I went back and checked all the squares, acording to one ruler OG, it was out by maybe 1/8- with QS it was perfect?So does that mean QS is wrong--since its my 6 x 24- (my main ruler) the other is a 6 x 6 square. I taped off the 4 x 4 area just to make sure, on both of the rulers? How is this possible? No wonder ppl are having problems with there laying flat of the blocks, and assembley? Now I'm in a pickle for sure because I use both ruler's when I quilt? When there is a 1/2 price sale and it on a paritular brand, I tend to choose the sale item, if thats the one I need. Why isnt there any stander-ziation in quilting? Why do some ppl call the blocks diffrent name, and its the very same block? This is drving me nuts, being that I havent learned all the termology for the quilts or the blocks yet? I did go back and re-cut ALL the squares with one ruler, hopefully you wont have this same problem? Any one else have this same problem, please dont say its me!
