Frog Clasps

Some time ago I blipped some knitting I was doing. Here.
Very complicated, very colourful, very long time to complete!
Anyway, I'm on the last leg.
I needed something special for the buttons and because I couldn't find anything I liked in town decided to make my own 'frog clasps'. I didn't know they were called this, just knew it was what I wanted for the cardigan. So I went onto the internet and hey presto there were the instructions! I've made 4, just another two to go!
