I have also been working on these blocks this month for the 4x5 Modern Bee.
I decided because I was going to spend a lot of time on the plane flying to Abu Dhabi that I would do a handwork heavy block.
Even with over 48 hours of total travel time, I still had tons to do when I got back.
Thankfully they take much less thought and skill than the "Killer Block".
The sides of the hexagons are 3/4 inch. I English paper pieced the hexagons together and then appliqued them onto the background.
I used a lot of 5 inch charm squares that I had gotten in swaps this year in each 12.5 inch block.
I have found that having a well stocked supply of multicolored "scraps" very handy in swaps.
And here they are all together.
Enjoy! Have a safe and Happy New Year!
