I’ve been teaching how to make quilt tops for about a year. I have found that most students have no problem making accurate cuts (as long as they read/listen to directions and understand them. It’sthe 1/4” Seam that causes most problems. After having pieces that don’t fit, they come to me and ask why. Seams are a fraction too big. Then I hear, “But I have a 1/4” foot!” They’ve never bothered to measure for accuracy. When a block has multiple seams, even 1/32” off can make a difference. With a seam containing 2 pieces of fabric, that becomes 1/16” off. If your block has 4 seams, now that block is 1/4” off. For seams that are off more than 1/32”, the discrepancy becomes even larger! Accuracy matters. Take your time to get it right. and remember...quilting is not a race. Slow down and enjoy the process.
