Put something like a 2x4 across it, step on it, squishing it down,
then cut with a utility knife (careful of floor underneath)... if
doing on cement (or regardless), blades will dull quickly, will need
many.

Odd. I looked back a few weeks, don't see the original post you're replying
to.

The way I did in the garage was with a pair of sawhorses and a full sheet of
plywood setting on some 2x4s as a table. Used a T-square as guide. A
little long is okay, any short is not.

i found a real easy way. Take the same piece of plywood mentioned here,
saw a 24" slot in it. Then hold your insulation down with a twobyfour next
to the slot and cut it with a bread knife through the slot. Works
perfectly! I used one of my ginsu knifes and have cut hundreds of pieces
this way.

I'll second this idea, I use a 4x4 on the bottom and a 2x4 on the top,
with the 4x4 clamped to a saw horse. The secret is that serraded
kitchen knife--a regular knife won't do a good job, or last, but even
cheap serraded knifes work well cutting insulation.

Just about anything that will hold the insulation and give you an edge
to cut against works well.

I suggest that you don't get too carried a way cutting
and drag that serrated knife across the back of your
hand. I have seen it happen.
