I needed to resize the diagram because the finished block would have measured 10"; I needed it to be 8". I did this by scanning the diagram and resizing it using an image editing software.
The way I made the block is different from what I was used to. Pre-sunflower-potholder, I've made blocks by making my paper templates, adding a 1/4 inch to all sides, and then sewing them together using a 1/4 seam allowance. Easy to explain but not always easy to keep triangles, squares, and whatnot, uniform. The technique that I learned by way of this calendar is easy to do. Try making a block yourself by following their instructions here:
Once I made the block and the quilt sandwich, I bounded the edges and added a loop. Done! And just three days before Christmas, too. Whew! Made it!
