If this number is too high then you may have to shop around until you find the right manufacturer who is willing to do the job for you.

Owing to concerns over the effects of such leachates, the European Union has restricted the use of dehp (di-2-ethylhexyl phthalate) and other phthalates in some applications, and the United States has limited the use of dehp, DPB, BBP, dinp, didp, and DnOP in children's toys.

I won't discuss wooden frames any further, because they don't get you the mix-and-match size advantage, and tend reduce the maximum size that will fit in a kitchen oven, but if you want to pursue that option, see this thread on m: my Lowes doesn't.

If you want to build a small standalone vacuum forming oven cheaply, check out my 30 oven design at m: p?t621858,. A 3/4" galvanized floor flange (plumbing fitting). (Having extra corners is nice, so that you can have some different-sized frames without having to take them apart and reassemble them when you switch sizes.).

If you don't already have one, you can get one for 5 at the Goodwill Outlet Store (a.k.a.
