I've just completed my bright and beautiful granny square bag.
It's made from a very large granny square - 60 cm in width.
It's lined and I bought some lovely plaited handles for it.
It's my new knitting bag and it's very roomy inside.
I based my bag on the free pattern from Pierrot Yarns. You can see details of the pattern, via Ravelry, here. The pattern calls for 4 ply yarn used double but I used double knitting weight yarn and a 3.5 mm hook which works out the same.
It's quite an easy project to make and the beauty of it is that you can really personalise your bag. I might add some flowers and tassels but I think it probably looks jolly enough as it is.
