I would love to be able to make a house this year, but I am still missing more than half my kitchen things, including baking trays (from moving house). Anyway, I tried to make one last year, and as the panels cooked, they curled! Anyone able to offer any solutions?
DH has a theory that the corners are thinner than the bulk once rolled out, and that's why they curl up. Ours curled in two spots - but both for the roof, so it worked out okay. Maybe sit something on the panels so they cook flat?
