you need to secure one side first
using either
1) staples
2) crazy glue (with a speed inhibitor so it dries immediately--I figured this out after the fact lol)
3) hot glue gun
all these works
just do it slow and secure the one side, and then pull REAL hard as you move slowly around the mold
fleece is better since it holds more resin, but I found that a tshirt-or sweater (non cotton) can work better since its a little easier to pull tight and cheaper
if you do this you may have to use tow layers of mat vs maybe only oen is you use fleece
also as quick tidbit use a colored fleece or tshirt its easier to see where you missed the resin
and if it does wrinkle not a big problem, you can always
1) just dremel it out and cover the hole with mat and resin (three or more layers sicne its a hole)
2) or just use filler, since its easier to sand than fiberglass anyway
less sanding the better though I still have blisters
and use proper tools
a dremel and a die grinder or small circular power sander ( Ididnt have one--and it sucked)
it will make your life soo much easier
AND MAKE SURE you have aimed your ribbons porpely using a laser pointer it really makes a WORLD of difference how they are aimed, I had to aim mine twice
