I can remember when I got my new machine with the little flange on the quarter-inch foot. yes, I jammed the fabric up against the flange, couldn't see where the edge of the flange was (bought a new light to take care of that), messed with needle position. Then I bought a new foot and took off the flange- the edge of the foot was rounded. Then bought a new see through foot with Square edges on the right, and that's helping me a lot.
All those teeny 1 inch squares on the 2009 and 2011 BOM taught me to be very careful! I still have not yet attempted a Lone Star quilt, but it's on my to do list. Plenty of starch and measuring will be necessary, I think.
My latest quilt is 3 inch blocks, 14 across and down. The quilt top actually measured 42.5 inches, just what it was supposed to! I did a happy dance!
