Sewing - project bags

I'm currently experiencing something of a black hole of knitting. This has involved lots of casting on, & casting aside of new projects, and completely re-knitting a cardigan that just wasn't right. In 4 ply yarn. After I'd already woven in ends & blocked the original. (I may have been in some denial about the cardigan's issues.) I have managed to get some sewing done though! I cut out the fabric for these project bags months ago & finally dragged out the sewing machine from it's toddler-proof hiding place the other day. The basic bag is made up from no particular pattern. 

They will come in handy for tidying away some of these knitting works in progress.
