Sweet Pea has ripped holes in nearly every pair of tights I have purchased her in the past year. I don't know what she is doing but it's making me crazy. She is a big fan of dresses so she wears lots of tights so this is sort of like the little boy who has holes in the knees of his jeans. Well, rather than run out and buy new tights, I decided to give repairing them a try. Here's how to do it if your girl has the same problem.
1. Start by having your girl try on the tights. Make measurement of how big the hole is and write it down. Then take a measurement of your girl's knee. Sweet Pea's was ten inches around. Divide that in have and right it down. Then take a piece of cardboard and cut it the same width as 1/2 your girl's knee measurement. The height is flexible. The one in this photo is 5 inches by about 8 inches. Round the corners of cardboard so it will slip into the tight leg.
Next take an old tshirt or cami and cut out some shapes. Makes sure they will be big enough to cover the holes or tears. Also, make sure that your t-shirt is a stretchy one with a bit of lycra or spandex in it.
