Put on some masking tape. Cut.
Peel off tape after layup.

They make stitched fiberglass so this does not happen.

Ahoy, I'm new to the fiberglass routine. I wanted to cut my 24oz WR
into 5 inch strips so I can lay it onto a vertical surface (topside)
but when I cut it the weave it all comes apart. I count't find any
ready made strip in this size. Is there a technique to stitch it up
and prevent it unraveling long enough to lay it in? Thanks.
