I had a brain blip the other night when i started on this set of 10. I sewed the to small shapes together & couldn't at first work out why i was short shapes when i knew i'd cut out 4. After an Ah ha moment i had a bit of reverse sewing happening & that was sorted. I got up to sewing the 3rd pair together only to discover i'd sewn the small shape to the wrong side of the larger shape. Again reverse sewing. I felt like giving up & going to bed but i persevered & got the block together. I started on a 2nd but decided i would give up for the night as i wasn't really in a sewing mood. But since then i've got stuck into them & have nearly all 10 done.
