That is the nature of the beast. 5" strips will be almost impossible to
keep together. Better to change to a mat backed bidirectional like DB1708
for narrow strips. It stays together much better and is a lot stronger.
One thing that does help is to cut it with an Ofla rotary cutter rather than
sizzors. You can get one at a fabric store for about $15. Also wet out the
surface and lay the roving on dry. Then fill the weave with resin. Neither
is a magic solution but they help.

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.
