This one looks nice. You have to register but its free. I have made a frog one

I tweaked the pattern and also made cat and dog ones and changed the pin cushion to a bone or fish.
Idea on what to use around the top of the bag - go to a £1 shop and buy a cheap metal tap measure, cut to size and bind together with masking tape. Or you can use the plastic packing tape - get the thickest you can - white good shops are good for this. Or another is the plastic covered wire that you use to hang net curtains. All fairly cheap. Hope this helps
