I am rather new to D&D but have played 3 characters (different classes) before I had to leave my group. Now that I feel well enough to return, I am working on a new character who's a traveling mute merchant. Though I have a few wording issues on things like cart vs wagon, I am fascinated with portable holes and how they can be used. After searching a few sites (and finding great results on this one) I would like to ask for more details about the use of these holes. (looking at 5e)
The idea I've been having about portable holes is questioning if they can be used as more than just huge pockets, and how effective they can be as storage. I realize now that I cannot ask all the questions I have individually, so in an attempt to unify most of them allow me to ask this:
Knowing that you cannot cut, modify or stitch pocket holes together, would it be possible to craft a square hole that has been mounted to a tarp so that, when pulled taut on a frame, the hole can be used as a portable room, say creating a portable bedroom or medical room you can carry around with you on your adventures?
