I leave in the northeast and often, household temps are cool enough that it impedes the bread products rising. I usuallyl make the dough in my breadmaker on the dough setting. After forming into pans, I then put the pans on a heating pad and put tea towels over the pans (medium setting). Within 45-60 minutes, the product is ready to go into the oven. Many years ago we had a heated water bed. Would lay a large towel on top of the bed quit, then nestle the bread pans onto the towel, finally covering with a couple of tea towels. That worked like a charm also.
Incidentally, I store my yeast in the freezer with no problem. Literally keeps for years and performs well. Have taken frozen bread dough out of the freezer, greased the bread pans and let it thaw and rise in the refrigerator. It all works, just takes longer.
