I need to go out to the pet store to get some new things. (Smaller hides, for prime example.)

I have a hard time trying to eyeball hides, so it's necessary for me to bring my BP with me...

I do not have a carrier, but he seems to be ok with being around my neck or in my sweatshirt pocket. I don't intend to do this a lot, but does anyone have any suggestions?

i do not have a shoebox, or tup-a-ware that I can put holes in (it's my roommate's stuff). I have a pillowcase, but I only have the one and I'm not sure if it would be ok to use it. It's clean but it's got some pokey needle-like things in the seams in the inside and I'm not sure if that is on the outside part as well.

I do not intend upon spending a lot of time out. Just a quick trip to the store and back. He has been fed and has already digested and pooped the meal, so I feel this won't make him sick. And I'll give him a couple of cool down days after before feeding.
