I carry what you do, usually my stencil/markers of choice for that project and rubber fingers. I toss it all into a ziplock bag and just roll it up in the quilt. I usually use a hoop so that makes a 'bed' sort of for the baggie; stencil; etc. But I like the idea of the 'pencil case'. Might just have to look for one of those as the baggies usually develop holes. I actually have several in a tote bag next to my sewing chair now for extra thread, etc.
