What exactly are stabilizers?

To those who have used stabilizers, they are a magic cure-all! They make the end result of all our creative machine work look professional so we can achieve the great look we desired when we conceived the project. Sulky Stabilizers, except for Heat-Away, are all non-woven so they don't stretch in any direction and they don't dull your needle like paper products can. They are available as permanent cut-aways or temporary tear-aways; some are water soluble or heat-disintegrating.
