Cut your material so that you have at least 1" of overlap onto the previously laid up section. Stagger the layers so you don't create a big lump. A trick that professional glass guys use is to tear the edges of the mat. This tapers the thickness down at the edge, making a smoother overlap. Done correctly and applied while the previous lay up is still workable, you wont be able to tell that the part was made from separate pieces of mat, instead of 1 continous piece. | Cut your material so that you have at least 1" of overlap onto the previously laid up section.

Here are a couple of troubleshooting pictures. The white streaks and crosses are the result of a slightly stressed part, this one was from the laminate being in the sun and curing too fast in that spot. It is the resin shrinking and pulling the fibers apart that causes that appearance. | Here are a couple of troubleshooting pictures.

Here are some air bubbles, center right of the pic, and a resin rich area. The fibers are almost floating on the resin, and the appearance is one of shiny, glossy pure resin,with a very low reinforcement ratio. The air shows up as misshapen, somewhat opaque objects in the laminate. | Here are some air bubbles, center right of the pic, and a resin rich area.
