I cringe when a contract customer sends us new era hats to embroider. Their structured caps are so rigid, you can have registation issues with the best embroidery machines available. We like flex fit and outdoor cap. Outdoor cap has sample packages you can buy that are great. You have a choice for basic, fashion, camo, etc. The packages are a great tool for your shop, very inexpensive for the sample packs. And when you're done with that years sample pack, you can offer them to customers either blank or embroidered for a discounted price.
