I like it! It's a neat idea combining a knit top with a fabric skirt to make a dress.
Your daughter is just loving your knitted creations!
I can empathize with your wanting to tweak! I feel like the more I knit, the more I want to tweak patterns to my liking. It seems the more you try new things, the more ideas you get and the better you get at making exactly what you want. This is what I like about this whole knitting thing! It's such a fun, creative process!
