I've been experimenting with reusing old clothing items to make new outfits for the baby. I've done a dress from an old camp t-shirt, and a romper from an old knit shirt. The dress turned out better than the romper. Probably because I made up the romper pattern and the knit fabric was more stretchy than I expected. Sorry, no photos of that mess. But she will wear it this summer. Even if the neck line is wacky and the sleeves gathered uneven.
I also tried out using a dress shirt for a dress. That turned out better. Unfortunately, she out grew it pretty fast.
Two weeks ago I finished an Easter Dress for her that I bought new fabric and a pattern for. I've decided I like reusing old clothing items, but everything turns out better when I use a regular pattern and new fabric.
