I tinkered with another backpack (Made-by-Rae sewing pattern), but then decided to opt for something different: a shoulder bag. I was going to do the messenger bag pattern from Oliver + S Little Things to Sew, then I copped out. I really didn't want to learn and follow a pattern. I'm rather lazy like that. (Then why did I buy all of these kids' patterns recently?) So I winged it. But he LOVES it. And that is so so rewarding. At supper, we give thanks and Oliver said he was "thankful for my great dinosaur bag!" So good.
