A pigeon, of course. (You were expecting a joke? Sorry.)
This is my latest self-published design (it’s a very short list!) – a simple mini messenger bag in two sizes, suitable for kids or adults who want to carry just a few things with the minimum of bulk. Linen stitch is pretty stable, so you won’t have to line it – and I’d highly recommend trying this with a variegated yarn, or striping to use up scraps, as this stitch also plays beautifully with colour changes!
Consider this as a quick Christmas gift, or a handy accessory for yourself. It’s free from Ravelry.
