Using stretch fabric is recommended because we can create a smooth wig cap. The left one is also using stretch fabric but I didn’t pull down too much so the wrinkle still existed. Use string rubber to hold the fabric and pull down the fabric until the wrinkle disappeared. After wipe it with glue and leave it over night, the glue will dry and the stretch is disappeared. You can take off the stretch string and cut the unused fabric. The wig cap will be thinner because we pull it but that’s ok. if you think, it’s too think, may be you want to double the fabric next time making wig cap. For me, 1 layer so far is enough.
