: Try sawing them in half (with a fine-toothed saw) and using a short roller base. It will save a little on the rollers, plus

Roger that. The 1/8" roller covers I have seen are 7" long, not the 9" commonly found in paint stores. Actually that works out really well, because trim roller frames are available in both 3" and 4" length. Buy one of each, cut the covers to fit and there you go.
