I have finally finished step #3 for the Orange Crush mystery. This step took me a long time, even though there were fewer units. First of all, I had to look at the photo to sew each and every piece together and make the mirrored units. In reading the other mystery quilt blogs, I was relieved to note that it seemed to be the same for lots of other quilters.
Secondly, my new sewing machine was doing the same thing it did when I strip pieced units from the first mystery. The beginning of every seam, on the underneath piece of fabric got bent over. So I had to unstitch the beginning of each seam and restitch just the first part of every unit. Luckily I realized this was happening before I had sewn them all! It I fed the units through the machine starting at the opposite end, it worked fine! I guess the beginning seam was too bulky? Anyway, they're done and I'm ready to start cutting into some yardage.
