Cutting Tips
Great advice from everyone, thanks! I use Omnigrid rulers, and sometimes
resort to my husband's very heavy t-square for cutting, it never shifts. I almost ignore the grid on the cutting board, it doesn't seem that accurate to me. I think from what all you have been saying, that the seams and pressing are the culprit, need to adjust for that. When there are many pieces in the block, the problem really multiplies. . . . I'm going to experiment, and practice new tricks and techniques. felwyn "felwyn" wrote in message news:... I will try that, thanks. It's a good way to see where the problem might be. Actually adjusting the seam allowance to a scant 1/4 in. is probably the easiest way to correct the problem, and it might not be the cutting at all. I think I will make a habit of doing this test each time I start a project and set up my machine. Thanks felwyn "Sandy" wrote in message ... In article , "felwyn" wrote: Does anyone have any rotary cutting tips? My finished blocks are always a little smaller than I planned, not much, maybe a 1/16th of an inch smaller, but over the length of the quilt, it makes a difference. All the blocks are equal, so accuracy is not the problem, but I wonder if I should cut a tiny bit more generously to correct this. My seam allowances measure 1/4 inch, so I think the problem is cutting. I would love to hear any suggestions and advice. felwyn Felwyn, I'm another who suspects your seam allowance of being just a trifle off, rather than your cutting technique. As Leslie said, you are so consistent that it should be a simple matter to figure out how to adjust. Here's how I was taught to check my seam allowance: Cut three strips of fabric at 3" x 1.5". Sew the three strips together along the 3" sides, pressing each seam, so that you now have one pieced "block". Now measure your block. It should measure exactly 3" square. If it's a hair too small, you know that your 1/4" seam allowance is a trifle too wide. That's where we get the "scant 1/4" seam allowance" you'll hear about so often. We all have to adjust for the thickness of the seam itself in order to create precise blocks.
