I am using a rotary cutter, it seems better for the endless squares P&Q requires. I cut out my garments with some fantastic Sheffield steel shears.
I don't need the 6 1/2 " squares yet for the patchwork pattern, so I've been working on my 4 patches (4 x 2 1/2" sqaures), which has mostly worked ok except for a few wrongly cut squares, and one block with an extra layer.....
Good use of the unpicker to sort the few issues out :-)
I should get my new square rulers Wed or Thu so can work out a sensible technique then.
