Ohoo! Glad you decided to jump in on the challenge! You really grasped the idea behind it! That was nice to read. And beautiful shots of your handbag :P

I used the time to think about a list and worked a bit ahead of schedule (the writing about part takes me the most time). Not sure if you noticed, but you already listed 7 potential ordinary items within this post (the stuff that goes -in- that handbag).

I'm guessing the strap is about 127 cm (OR 154 cm if you were taller).
