too vague. have you looked on Pinterest at 'craft rooms' and seen any that might work for your room? you know what would work, we don't because you haven't posted anything.

go grab some ideas from Pinterest, then copy those photos that you like, come back here and post them w/a photo of your room.

or maybe you want to do a big work table

I've got a similar problem, and I've been thinking cube cubby shelving might be best for organizing a lot of my supplies. What's really fantastic for art and craft supply storage is restaurant supply sheet pan racks:

As shelving, the pans hold a lot and there's flexibility in the height between them. The racks are on casters so you can roll them around AND you can find them used for a good price. However their appearance is utilitarian and may not blend with formal areas of your house.

Well sweetie. It's a total MYSTERY MEAT with no photo, no drawing no dimensions and no anything. We're not there. We are here. Clueless,.... : )

Also, it is YOUR studio/workroom, what do you need to make it work? Flooring may be an issue, esp if you have wall to wall carpet, hot glue, solder, paint etc. Lighting, storage, work surfaces, ventilation.....I wouldn’t bother trying to make it match the rest of the house, but I would think it would if you are a creative person who has already put their stamp on the rest of the space?

IMO this is a bedroom so it needs a closet if you are thinking resale down the road so put the closet in fill it with proper storage of all the stuff you use and close it whan you are nort working. Add a nice work table that can double as a desk have a place for all the stuff that creates a cluttered mess add some great lighting , I happen to like track lights for work rooms since you can have the light exactly where you like , paint the walls a color you love add a really comfotable work chair . I lke the stainless shelving on casters if your work needs tons of stauff at handthen back in to the closet when you are done.Make the closet fit your needs so take the time to really figure out exactly what you need to store , what needs to be at hand on moveable shelving it will take some time to get it right but you will end up with a nice space that functions well and a proper bedroom when the time comes to sell.
