Thanks Quilt E for the information. I will try lowering stitch further. I was afraid the triangle square might pucker if the stitch was too tight. I've only done HST (and not that many) by sewing 1/4 inch on either side of a line. I have to make 200 for a pattern and thought the paper would be easier but I wasn't happy with my practice pieces. The few tuts that I looked at never addressed the stitches coming out...just said shorten the stitch length...which I didn't do enough. Again thanks for the help.
