DELICATE HOLE REPAIR
A nice hole in a cute dress.
Find a scrap of fabric similar to the weight and color of the fabric you are repairing a hole in. Cut a same size piece of "whisper weft" or interfacing with glue on both sides.
Place whisper weft in between both layers of fabric and iron it. Make sure the glue on the interfacing melts to hold the two layers left. You can leave it like this without any sewing, but if you plan on washing the item a lot I would recommend sewing one set of stitches around the edges going with the grain.
Good as new!
