Picket Fence Quilt Block

My mom called and asked me to make a quilt for our family reunion auction in August. She acquired five quilt blocks and some fabric from a friend of hers who is moving. So I told her I would do it. She mailed me the blocks and the coordinating fabric. I've been working on this project and have 17 blocks made. Last night, I decided I should create three blocks of my own. Since the reunion is going to be where I grew up, I started thinking about ideas I could do for blocks. We grew up with a white picket fence around the yard. Some of the flowers in the yard were purple Irises. So, I came up with the first block of my own. Now, I don't recall "red" birds in our yard, but the color was good for the block. So.....here's my 1st design. This makes block #18.
