This is the block that I plan to do next! It's so beautiful and I love Jenny Doan's easy instructions for any block.
Your block is lovely. The red you chose is vibrant and matches well with the print. Don't worry about your points. The best way to get them straighter is with practice and patience. My beginner quilt blocks looked similar to yours and they are proudly on my couch and bed, and they get me compliments all the time. Now my quilts have much better points and I credit that to learning how to do a better 1/4" seam as well as having more confidence in what I am doing.
Are you planning to do all of your blocks in the same colour scheme or are you going to alternate colours?
Keep it up, you are doing a great job!!
