What a task that was for me.
I haven't done a lot of paper piecing before this and found it quite difficult to complete the block.
First of I redrafted the block in CorelDraw and then printed out a ½ dozen copies and started sewing but for the life of me couldn't work out why it didn't look like it should, slowly the penny dropped .... I needed it to be mirror image. Once I redrew the block I started moving forward.
I did it in 5 rows and then sewed the rows together. The top and bottom row was done in 1 piece, but 2,3 and 4 were done in 3 pieces each and you really don't want to know how long it took me ... alright about 6 hours not counting minutes. I really do hope that the next challenge is a little easier.
