Fusibles are used to join two fabrics together in either a permanent or temporary form by melting between two layers of fabric. Which product you choose will depent on what you want to accomplish with fusing. For example, Steam-A-Seam and Steam-A-Seam 2 are two possible products to use for machine applique and embellishing. These products are tacky and allow you to move the pieces, they are not permanently 'glued' until ironed.

There are also heavy interfacings that are fusible, these would be used for items such as fabric bowls, boxes or bags. Each product comes with manufacturer's instructions. If the fusible is not adhering to your fabric, washing the fabric will usually remedy this problem. Caution with a hot iron is important when fusing two different kinds of fabric because of the different iron temperatures the fabric will tolerate. Testing a sample is always in order. Protecting your ironing surface from getting bits of glue on it and watching for glue and removing glue on the soleplate of th iron are small drawbacks from using fusibles.
