Hi all, this is my first time posting here! Id like some advice... I've made a run for my 3 piggies and made up the correx 'trays', my next job is to make the fleece liners, but I don't know whether to sew sides on or not! I like the idea of nice neat sides that fold over the edges of the correx to keep everything in place, but my mum and hubby thinks it'll be a waste of time and effort. Can anyone give me advice, or let me know what you'd recommend? Thanks :-)
