Here's a quick trick to rolling them smaller.
Take a couple of plastic cutting boards. Lay one down on a counter or table or some other steady surface.
Place the wick on top of that cutting board taking note of the direction the wick is roled in.
Put the other cutting board on top of the mesh so you essentially have a wick sandwich

.
Put light pressure on the cutting board and push it in the direction that the wick is rolled.
Repeat until the wick is the right size.
Keep in mind you just want enough pressure to roll the wick down, you don't want to crush it
