Add-on sleeves

Katy picked out this super cute dress for Easter but it didn't have any sleeves. I know it's not a huge deal and most people aren't bothered by a sleeveless dress for their daughters, but it bothers me. We fight whenever I ask her to wear either a shirt underneath or a sweater on top. I don't know why she hates it so much but I'm kinda tired of battling that. So I found this awesome tutorial(https://www.sewcanshe.com/blog/2018/3/23/add-a-diy-sleeve-to-any-dress-free-sewing-tutorial) on how to add sleeves to ANY dress/shirt. Sh's figured out all the sewing math so all you have to do is measure your dress and plug in those numbers. I tried to match the color of the dress with some silky and tulle-y fabric from Joanns. At 40% off it cost me $3 for 1/2 yard of fabric. I think it turned out great! And it wasn't very difficult. Now I need to go through the rest of her dresses!
