This trendy 18mm Iron-On Double Row Spike Trim will give you that rocker chic look you've been craving. This trim is made of a felt ribbon with two rows of faceted spikes. The back of this trim has adhesive glue that can be attached to most fabrics. Avoid using this trim on leathers, vinyl and plastic materials. To attach this trim simply lay the trim on your desired fabric, and place a piece of cloth between the iron and the trim. Leave the iron on top of the trim for 1 minute so that the adhesive glue melts and attaches the trim to the fabric. The iron should be on high with no steam. This trim will look fabulous on t-shirts, the hem of a short skirt or your favorite clutch. Create your own DIY accessories with this fashionable trim. Available in four colors.
