The first block is from Elizabeth Dackson of Don't Call Me Betsy. This block is called Patchwork Wheel, and a link can be found on her blog.
The second block comes from Jeni Baker at In Color Order. This was the December block for her Block of the Month project.
Both of these blocks were very easy to put together and consisted of mostly half square triangles. These were very rewarding blocks - because they were being created for a great cause, but also because of the speedy process. I will definitely be making these blocks again in the future!
