Apparently I am feeling sew-y today. This was quicker, maybe two hours and probably faster now I know how it's done.
This is the Flea Market Bag by Grand Revival Designs. The fabrics are Amy Butler (Daisy Chain collection, I think). No messing around with this one, er apart from the bit where I didn't quite read the pattern right and cut the straps too short then had to add a sewn extension, so there's some extra seams. It wasn't terribly complicated once I understood how the straps worked. I'm going to try the Practical Bag from the same company as well.
And now, I think I need to collapse on the couch!
