So did you ever have a idea in your head, get everything you need , then cut the top of your thumb off cooking dinner and can't do it? No? Just me then...lol..
This has been on my "To-Do" list.
All you need is:
A Shoe- it doesn't need to be a high heel
A Sock- not a nylon, your putting pins in it
And Sand- Keeps the needles sharp and it weighs it down.
