I just finished my first quilt block, and instead of 12.5 inches square, it is approx a bit over 12 by a bit under 12.
Looking over it I noticed that it is a mixture of slightly miscut strips (That I didn't notice when cutting) by some slightly uneven, not exact seams.
When I started the block I was not sure what I was going to do with it, and now I'm debating on doing a bunch of random blocks and putting them together in a lap quilt, or make a pillow out of the one block.
Is there a way of getting the blocks more even. On the sewing machine I have a stack of masking tape at the 1.4 inch mark, but still tend to go bigger and smaller then that.
With cutting, even if I move the hand up the ruler while cutting, I still get either the ruler or the fabric shifting.
