Jane, My advice to you is to print out the templates..use them as a guide to cutting the fabric larger than the template itself at least by a quarter of an inch..use a glue stick when placing the fabric on the pping section when adding another piece of fabric , line it up then pin on the seamline and flip it to see if it covers the section it needs to cover...if it doesn't, re adjust it so that it does before you stitch with the machine..I do this with every piece of fabric..
Don't give up.. Do me a favor and work on block # 79 "Patience" using the pping method.. cut each piece of fabric 3 " square..This is a very easy block to make..when you're done , post it here..
AND, for any others new to this way of sewing blocks do the same as I've asked Jane to do...
