Heather, those papers can get kinda expensive! Plus they are on the small side, which might be fine for tiny or short objects!
Lowe's did have 2 'x 2' sheet rock panels, cheap, cut already so not some big 4 x 8 panel to try and get home...in a car, and I could repaint one over and over and plaster. Fabric is a maybe too, particularly the remnant tables.
Someone is supposed to be 'giving' me some studio lights that he doesn't use anymore, I have no idea how to use them but of course I said 'yes'! I'd love to have them...I know at some point I do want to focus on some still life and maybe try a real 'live' person.....maybe ;o))
