My idea was to sew the flashes right onto my sock. I would only need 4 5" pieces of material this way and wouldn't have to buy the adjustable things that go around the calf or even buy velcro. I have no money to spend at all. I'm looking for some discarded material around the house I can use if possible but something that won't wrinkle as easy when it's in the wash. I was thinking of a linen type of material that they use for tablecloths etc. in most restaurants might do the trick (doesn't seem to wrinkle as much as other materials). I was going to simply sew then onto my sock with just a simple hand stitching. My socks were over the calf and I have about 5 pair of them so if this doesn't work I don't mind just throwing it away. Does this sound like it might work? Also are they about 1.5in wide typically? I'm just going to start with black material that will go onto my white socks. Later on if this works will do a red material onto my black hose socks.
