These are not as difficult as I had imagined. I had several good books with wonderful patterns and ideas, but it was after watching a YouTube video/tutorial on the channel called "On Point" that somehow got me inspired. Apparently the planets were in alignment and I just jumped in and started. The 3 YouTube tutorials suggest freezer paper but after working with it, I went to Mylar plastic pattern pieces, and then made photo copies of the pointy arc. The pattern pieces came from a Karen Stone book.
These blocks finish at 7 inches, I need 36. The pieces in the photo are on a flannel board - no decision yet on a setting.
My goal is to make 2 blocks a day. However, one day, after listening to latest horrible political news, I was so frazzled and upset, I made the block wrong 3 times, miscut, missewed, trimmed wrong, and finally had to throw it out. That partial jaggey piece in upper right is another example of WRONG after listening to news - I cut wrong, tried to tape it back together, unsuccessfully.
I was able to finish one block in about 20-25 minutes - see? not really hard. Just go slow, a few stitches at a time, use something "pokey" to assist with the curves, concentrate with that paper piecing, use starch to stablize the bias. The paper on the teeth part is regular copy paper - works fine.
I followed Karen Stone's suggestion on fabrics, using just 5 in each block. Black and white, white and black, turquoise, pinks, and purples, but used a variety of each color, and am not introducing other colors.
