Have bag, will travel

I am traveling and brought along a new project. It's the Dr Bag from Knit 2 Together. I'm calling it that because it's a shorter version of the Doctor Bag. I'm using the recommended yarn--Manos de Uruguay--but I'm not double-stranding it. I really don't need a bag that is as huge as the one in the original design, but I love the herringbone stitch and the shape of it. Using only 1 strand, I'll be getting dimensions that are about 80% of the original. Plus, I can use less yarn, which is good, because it's pretty pricey. The herringbone pattern is supposed to be 8 rows to create each "zig" and "zag," but I've done 12 rows for each instead to make up for some of the visual impact lost by using single instead of double strands. This is a really fun knit for me. The only thing I'm worried about at this point is that the resulting knit fabric will be too floppy to hold the shape--I assume it would have been a lot more stiff with 2 strands. I think this can be remedied by putting some plastic mesh stuff and a liner on the inside, or by adding boning as Monique did, but we'll see.
