My $5 brotform
I discovered this forum when searching the web for a reasonably-priced brotform basket.
Finding none, I read some of the earlier brotform posts and realized that this baking item seems to be universally overpriced.
Decided to take matters into my own hands. It worked!
Grabbed a roll of 7/16" OD x 20' vinyl tubing at Home Depot, $5.55 with tax. I am confident this stuff is food-safe - I have used it for years for brewing beer and it's what moves air and water in millions of fishtanks around the world.
Washed it, then stuck it in a 200 degree oven for about 10 minutes. This made it pliable and easy to coil. Carefully wrapped it around the outside of a medium sized mixing bowl to form the shape. Then spent half a DVD movie wiring the coils together with coated florist's/craft wire. The finished form is around 8" wide and 3" deep.
Took some time but saved me $25.
Used it to proof my standard house recipe - found here. http://tinyurl.com/37wsgn 
The loaf is quite beautiful but next time I think I will use more flour in the basket to make a better color contrast.
I plan to make another but will instead use stainless wire since in hindsight, I am not so sure how the green craft wire is going to hold up.
