I purchased my muslin and I had help with cutting my squares. The muslin was folded twice the folded again to be able to get 4 squares cut at one time.
The mistake is that I didn't notice how it was cut. I have looked at a few of the squares and the material seems to look the same. I guess this sounds dumb but, is it real noticable?
I'll try using a 1/4 in. seam and will get back to you. Will you be online tomorrow?
