I'm a fan of the VPA 3 blades, if you have the setup to push them. Superior blood trail to 2 blade or 4 blade with small bleeders. Incredibly easy to sharpen as well.
Pillowcases work well. If you want to sew up something, have a look at monolite. Extremely strong and so breathable many use it as a bug mesh.
