I was doing a google search for a pattern for a hobo bag - I had a request for one. And I ended up on here, looking at tinafish's tutorial. I just have to say that you guys are crazy fun! I have never seen so much crafting going on! I have been looking at all of your pictures for the last 3 hours. I was supposed to go to bed early tonight. I will be doing the hobo bag shortly (and will post pics).
In the meantime, I thought I would share my usual fare...a diaperbag and a purse. The diaperbag includes two outside pockets (great for bottles, keys, sunglasses, etc) and four inside elasticized pockets, (two of which are for diapers and two for bottles, medications, etc). All the straps are adjustable and removeable. You can carry it as a shoulder (messenger) bag or a backpack. It also includes a matching changing pad, easily accessible in the front velcroed pocket. The opening has a zipper, the front flap veocroes as well.
The purse has a magnetic snap closure. I have also used a ribbon or a button when making it reversible. Enjoy!
