We've got organic cotton tote bags which are strong enough to carry your goods, but light enough to squish up nice and small and not take up much space in your purse - you can always have it with you!
We did our screenprinting at a place in Vancouver called Blim, which is a great resource - they are a Community Based Art Resource Center which facilitates screen-printing, button making, drawing, knitting, local underground audio, film screenings, animation, video, dance, spoken word, visual art, creative workshops, and crafts in the independent field. You can take workshops to learn everything you need to know about screenprinting, and you can book time in their studio space. For us urbanites living in apartments, it's perfect- we can do all the messy stuff at Blim! Definitely a place to check out if you're local and wanting to learn about screenprinting.
