Is your cutting mat wearing out?
When we repeatedly cut along the same line, it does get a little worn out. So we naturally want to move to a different spot to cut. For a white I just start and cut one inch farther down the mat. But after a while, I find myself counting inches and wasting time. So I mark the new cut lines with a sticker at the intervals I use the most. Of course, since I am cutting kits and yardage, I use larger measurements--like increments of a yard, such as 1/2 yard, 3/4 yard, etc.
But when I am cutting for a quilt, I usually am cutting smaller strips and blocks. (I love small pieces, don't you?) So when cutting for piecing, always use your ruler to measure, not your mat. Your ruler is going to be much more accurate. Place your fabric randomly on your mat to avoid the worn cut lines, and use your ruler to measure.
That's today's Tip. Have a great day. Happy Quilting!
