Hancock, and probably other fabric stores, will give you all the cardboard you want free!!! As they empty their bolts, these boards are stored under the cutting table and are disposed at the end of the day. They gladly give you all the boards you want - saves them work at the end of the day. I've been getting them from Hancock and Walmart for years. ALL YA' GOTTA' DO IS ASK. :>)

I go to Hobby Lobby to their art department. Thee you can find cardboard pieces that are slightly larger than a fat quarter. Using the measurements provided by the member in Alaska, sorry I can't remember her name, you can get 20 smaller size cards for your small fabric pieces and a nice combination of large and small cards when trying to cut the larger size. I use an old rotary cutter which makes the process very quick and little waste.

[quote=alikat110]What are these boards???

I just spent almost a week reorganizing my fabric. It got to the point that I had no clue what I had. I bought the foam board sheets at the Dollar Tree....Price check...1.00 each..lol. I cut them up into 6 X 5 cards. I used them for anything that was less then 2 yards. I have a lot of yardage also. I went to Home Depot to buy Corplast sheets. They sell for about 6.00 a sheet. They are in with the cut glass and yard sale signs and driveway markers..asle 9. I cut the corplast into 12 x 7 cards. I used a large rotary cutter to cut both. I am not completely finished yet..but things are more organized. I have batiks yet and several boxes of fabric that are complete lines for future projects.
Price Check..DH and I were in Dollar Tree one day and a cashier who was in training asked over the intercom system...Price check on such and such item. Everyone in line cheered out ...1.00..duh.
Happy organizing..
Peace and Blessings

I have done the same thing and I am really pleased with the way it looks and the easy way to organize it.

Matboard can be archival or not and, of course, it's not marked. You have to ask if it's archival (or conservation or museum grade) when you buy it and it will cost much more than regular. Regular is made from wood pulp and goes for around $6 for a 32x40 sheet (half that for thinner sheets). Archival is made from cotton and is close to $14 per sheet. (Foamcore also comes both archival and non-archival)

go to your local fabric store. I got a BUNCH

I use foam board I get at the $ store, but somepne here sells the core boards. Check the for sale ads.

go to your local fabric store. I got a BUNCH from Jo Anns. They throw them away. I cut mine down a bit, but they work great... Good way to recycle.

regular card board from fabric bolts is not the best way...the acid and chemicals on them is not good for the fabric! if you must use them, cover them in freezer paper first!
