I've been seeing loads of different tutorials for juice/milk carton coin purses online lately, and despite having loads of more sensible things to do last night (like folding and putting away laundry for instance...) I decided to have a go at making one.
This version from Family Fun is my favourite of the versions I tried, as it doesn't involve removing and reattaching the plastic thingy. I'm all for easy fixes! It also opens up nice and wide, making it easy to get your money out - and let's face it, nobody wants to be that annoying person that holds up the queue at the till!
You can find the instructions here if you want to make your own.
