Legging resurrection

I was going through my daughter's dresser and found several of these leggings that had become too short and had holes in the knees--but still fit her at the waist.

I've also confiscated a few of my son's T-shirts that have become too small and also have holes in them. So I cut circle ruffles from the T-shirt to apply to the leggings.
Here is the finished "new" pants with ruffles and a heart shaped patch.
