``Cutting and styling the hairpiece is almost exactly like cutting and styling the natural head of hair . There are only a couple of important differences:

The main thing you MUST do is keep the hair fairly long where it hangs down the sides and back of the head.

Start an inch away from the base material of the hairpiece, and thin away about 10% of the hair using thinning shears. Proceed a little further away from the base and thin another 10% of the hair away. Proceed on out the strands of hair another half inch, thinning another 10%. Keep doing this until at the very ends of the hair there's very little hair left.

The idea is to make sure there is NO DISTINCT LINE where the hair from the hairpiece starts. It should be totally feathered in. If this is done correctly, even drastic color mismatches or drastic texture mismatches are not even noticed at all.``
I`m NOT a stylist so just post it here for information purposes. I`d prefer a `professional`to do my cut-in, but for those braver than me...well, maybe food for thought ?
