Hi there.  I  made a holster for a leatherman + small flashlight.   It was my first leatherworking project and I unwisely stamped, oiled, and sewed it before adequately checking the fit for my leatherman.  At present I can force the leatherman into the holster, but it takes a great deal of effort.  Can I moisten the leather and let it dry over the bagged leatherman to stretch it out and form fit, even though I've applied the oil?
