This probably will get kicked but I want to make a hood for my highboy and am trying to find single ply? cardboard large enough to make a pattern....anybody here have an idea where I can get something bigger than 8x10......or some other material for pattern making.
I have used poster board. Got it at art supply place was approx 4' x 6'. Old political signs work great also.
I'm not familiar with the businesses in your area. If there is a corrugated box company or a Die Cutting job shop, you should be able to buy a few sheets of .035 chipboard. We own a die cutting company here in Maryland. We have several about 10 skids of that weight chipboard in 48" x 84 " ( 4 foot by 7 foot ) on hand all the time. Sizes may vary ! You also might try Grainger. They have a lot of product like this. I went through Thomas Net and found these companies. Good Luck https://www.thomasnet.com/southern-california/die-cutting-22510804-1.html
I got some that’s 48x40 for separating layers on pallets. It’s like a 12pk soda can carton material. That shit is great for pattern materials. Check with shipping and material handling supply places.
I lie the cardboard interior shops use. You can bend it in a brake and it’s sturdy enough to hold itself up
As toxic waste said, Hobby Lobby carries a heavyweight poster board that’s about the thickness of shoebox cardboard, but it’s only about 32”x42”. I use quite a bit of it. It will hold shape better than plain old thin poster board.
Picture framing mat board is about 1/16 thick if you want something that is sturdy and takes sharp pencil lines really well. standard size is 32 x 40, oversize is 40 x 60. Your local frame shop may have some marked/damaged matboards they'll sell you cheap.Hobby lobby sells the standard size only I believe. Unless things have changed since I was in the business, Bainbridge fabric mat boards use to come packaged singularly in a plastic bag with a sheet of chipboard over the fabric side for protection. That chipboard is throw-away stuff for a frame shop, so you might ask about that as well.
It comes (2) 48" x 96" sheets when I order one 48" x 96" sheet of 20 gauge sheetmetal. Last week I threw 2 old sheets away because they were wrinkled. Its hard to find a place to keep them dry and straight around here. Gene
