Ok I know it has been done but I don't know how yet. When you look at some really nice carbon pieces often you see a nice joint between two pieces of carbon that has been placed in the mold. It is obviously not just cut with a pair of scissors and layed down.

Are the two pieces stitched together like  seam in clothing. So that once layed down the frayed edges don't show because they are inside the laminate?

Lets say you are going to place your carbon cloth in a bowl shaped mold. If you cut your carbon in triangular shapes and put them in your mold you would have a freyed look at the joints.

Any advice.

Thanks

To add to that, I saw you mentioned the carbon tape, a strip of that with spray glue along the seam sounds promising too. You may need to take added thickness in account and work that into subsequent layers.

You are probably best off trying some pro-finish!
