I have a four year old granddaughter and See Kate Sew's Viewfinder Tee is perfect for her. The pattern is comprised of four pieces. I had my design, "Loopy," printed on Spoonflower organic cotton knit which is comfortable and durable. I chose size 4T. I thought I would be able to whip this up in an afternoon but I hit a roadblock with the sleeves. For the life of me, I could not understand that step in the instructions pertaining to the sleeves. I contacted Sprout Patterns and Caroline was so helpful. She sent me a photo step by step so that I could actually visualize the process. This helped tremendously and I was able to complete the project. My granddaughter loves Loopy.
