What are you most proud of? How the cup holder turned out. I had a clear piece of thick plastic that came from a gift box cover so I used it for the inside of the cup holder to keep it sturdy. She had a cup that she always used so I didn't have to worry about making the holder versatile. What advice would you give someone starting this project? The cup holder was a challenge, maybe because I'm a beginner...take your time and try not to get frustrated.
