Irish Chain blocks, narrow sashing, and not many of the alternate block usually used with the Irish Chain block.
I could quite happily spend all day playing with quilt designs in Electric Quilt … pity there are other things I love doing just as much! At the moment my EQ time is being spent trying to sort out my block library, which would be progressing really well if I could stop adding more blocks to the collection!
If I ever get sick of that, or finish(!), I will turn my attention to project files, like this one, which could use a colour change.
