I made a Lucy bag (
http://www.blackberry-ridge.com/lucybag.htm), and the bag felted faster than the handles, which are all stockinette except for the very edges. When the bag was felted perfectly, the handles still curled and were not felted enough, so I put it through another cycle. The handles came out really well, but I almost cried because the bag looked way too shrunken. I was lucky because my husband and I were able, after a lot of really strong pulling, to stretch it over a big plastic bottle that was just the right shape, but I should have watched it more carefully during the second cycle.
