Up to now, I've been carrying my £1 coin and a trolley coin in a (free) plastic coin holder but last week it started dropping the £1 coin out - not good. I decided I wanted to have something that would hold the 2 coins safely but would be small enough to hang on my keyring.
I used the tutorial for the ear bud holder from here. I made my circles 3" instead of the bigger size needed for ear buds and here's what my teeny tiny purses look like.
I made one for myself and then, when it worked, one for Jo as, most Sundays she has to ask me for a £1 coin as she never seems to have one. Now she won't have to ask as she can attach her teeny, tiny purse to her keyring too! Very cool! :o)
