Depending on your printer and the weight of paper, it is not uncommon to have to hand feed the sheets :wink:
Are you shortening the length of your stitches? I use regular copy paper, shorter stitches and the paper tears very easily.
By not shortening the length, the paper will be more difficult to remove. It also helps to keep the stitches from coming undone at the places where you trim the blocks :D:D:D
