I love to paper piece. I find it a "no brainer" since the pattern tells me where to put ea. pc.
I found what helps me is to hold the paper pattern up backwards against a pc. of picture frame glass (8x10) to the light or window & trace around it with pencil. Puts the pattern on both sides. Takes the guesswork out of where to sew ea. pc.
Has anybody mentioned yet about the Add-a-Quarter ruler? There are 6" & 12" ones. They have a 1/4" lip on them & you lay them on a seam after sewing 2 pcs. together to trim. There is also an Add-an-Eighth ruler but I don't have that one.
I found the easiest way to release the paper is to gently stretch ea. section til the paper tears away from the seams. Be sure to use the paper especially made for paper pcing. It's thinner & easier to use than reg. copy paper.
Hope you love paper pcing.
