I made some of these shirts last March, but needed to make a new one for Taylor's first time to the "happiest place on earth." It is so easy to do and so cute for Disneyland. It's best to find a shirt solid shirt you already have and some scrap material. I turned the material to the back side and drew with a pen a mickey mouse head. Then I cut it out and pinned it to the front.
Then I sewed it along the edge about a quarter of an inch in.
Then I made a sparkly bow and sewed it to the front and now it's a Minnie shirt.
Below is one I made earlier and I embroidered Minnie Mouse to the front also.
We went to Disneyland with my Mother-in-Law so I made her one to match us :).
And here they are in action!
