Here's what you need to make your own 12.5" (unfinished) block:
Fabric B - a pair of 1.5" strips in each size (5.5", 7.5" and 9.5") and one 8" square, cut on the diagonal
Fabric C - One 3.5" square for center
Begin by attaching the strips to your center block, starting with the shortest strips (3.5x1.5"). Unlike in a Log Cabin Block, where you move clockwise around the central block, you attach the strips on opposite sides. I found it helpful to press seams out from the center.
All finished with the sewing, now we just need to square it up and trim.
Place a 12.5" square ruler over the block. The center of the green square should intersect the 6.25" vertical and horizontal lines on the ruler (you can use washi tape on your ruler if you need a more defined line). Can you see the spot I am pointing to above? The ruler should also line up with this point on all four sides, or pretty close. Hold your ruler down firmly so that it does not shift as you trim the four sides.
I love how they look together! I can't wait until the bee blocks start to arrive from my Haven Hivemates.
I hope you enjoyed this tutorial and if you make something from it, I'd love to see it in my flickr group. Thanks!
