Charity - the one on the LA is Snake River, it's a modified log cabin design. None of these are my own design - mostly I find pictures of something I like and then figure out how to make it. Except the Sylvia's Bridal sampler (last one pictured)- it's one thing to figure out one block that is used 50 times, but not figuring out 50 blocks that are used one time!
Happylab, I did not purchase a pattern for that one, but it's real simple as it's only two 3.5" blocks (unfinished). I used a row of 3.5" blocks to break it up a bit.
The best part of going scrappy, you don't need to know the yardage - and often that is the hardest thing to figure out without a pattern that tells you what you need.
