These hoops, like all HOOP IT ALL hoops, use SIA™ to hold your project in place while you embroider. What these hoops have that others don't, is a clamp that can be used for holding baseball caps in place and other difficult ltems. These hoops are not just for embroidering on caps. They can embroider anything that will fit in the embroidery field: including dog collars, baby socks, cuffs, shirt collars, belts, webbing, garments, sport bags, etc. The clamp for the Cap Bill can also be used to secure belts, bags and other similar items.
The medium cap hoop was made to embroider the sewing Field (uaually 4" x 4") of your machines stock medium size hoop. With HOOP IT ALL's superior design and cap clamp, doing embroidery has never been easier to do on regular every day items and Caps/ hats.
The BIG Cap/hat hoop was made for machines with sewing fields of 5" x 7" and replaces your machine's (large) Big hoop. These hoops are similar to their medium counterpart, but they allow you to embroider larger designs.
Our BIG MULTI-USE Cap/ hat hoops were made to provide an even larger sewing field that some machines are able to do. with just one hooping. They allow you to use the maximum size sewing Field that your machine is capable of.
