My DH is currently building me a sewing room. In the meantime I have picked up so many pointers on what I need. I have seen beautiful pictures of other sewing rooms. In several of these pictures, I saw material wrapped around what looks like cardboard. In fact many seem to be like the bolts in the stores but not as thick. What do I call these and where can obtain some? Can I make them myself?

If you go to a fabric store and ask for empty bolts they will generally give them too you. It keeps them out of the trash.

I went to a sign shop and bought a 4x8 sheet of plastic cardboard..(not sure what the proper name is.)for 12.00 a sheet. Brought it home and cut it down into 48 big pieces. I have used all those up and will go back and get two more sheets :D

Fabric stores will give you their empty bolt cardboards. I'm not sure if they are acid free.
You can buy comic book boards on ebay in lg quantities that are acid free & right size for wrapping fabric.
Some mentioned on this site, buying thick poster board or thin foam insulation sheets & cutting to fit your size preference.
Another way to wrap without a board, takes less space, no cost, is to do this:
Fold fabric selvege to selvege. Wrap piece of fabric evenly around a ruler, I use 6 x 24 ruler I use when cutting quilt strips.
Slip out the ruler.
I fold the fabric in half or thirds at this point; fits just right on my shelves.
Use smaller ruler for FQs.
Occasionally open fold & fold opposite way to prevent constant crease in 1 spot.
Best to cover shelves (I use old sheet) so sun doesn't fade fabric at the fold.
You should get many suggestions - its a frequently discussed topic here.
Also try the search at top of board & look for how to fold fabric.
Here's a tutorial on folding using your ruler:

I think the ones you're talking about are the coroplast boards. Somebody here on the board sells them pretty reasonable and you can get them on ebay and Clotilde has them too but they're a lot more expensive from Clotilde.

I found the seller here on the board,

Your right!! That is what the fellow called them. I got 48 of the large size for 12.00 out of one 4 x 8 sheet.

Go to comic book store and ask for their boards, 100 for 6.99 - 9.99. Work good also

I also like this idea and I ordered some from Amazon, I think it's a good inexpensive way to keep your fabric nice. http://smashedpeasandcarrots.blogspo...me-studio.html

I puchased comic book cardboard acid free etc. It works really well makes fabric bolts very nice. There are a few topics on here and one in the tutorials about using corrigated plastic (like political signs) Alaskasunshine I believe is her name.

these are what I use; although I tape 2 together for the strength.
