This is the basket weave block (no. 4) from The Farmer's Wife Sampler quilt. I figured it was a nice easy one to start with and to ensure I knew what I was doing.
Sadly all is not right with this one ... looks like my 1/4" foot is slightly wider than 1/4'. Having cut very, very carefully (lots of spray starch and pressing!) and sewed very slowly the block is almost half an inch shy of the intended measurements.
Even if it is too small, it looks good I think.
Off to work out exactly where I have to sew to get a perfect 1/4' seam allowance and mark up my machine accordingly.
