Yes, lace front wigs can be sewn in. There are a few things to keep in mind when sewing in a lace front wig, however. First, the wig must be properly secured to the head so that it does not move around or come loose during wear. Second, the stitches should be small and tight so that they are not visible through the lace. Finally, the wig should be sewn in using a high-quality thread that will not break or fray easily.
