What is Lightweight Fusible Interfacing?
Interfacing means a type of layer within or on a piece of fabric, which has the effect of providing structure, rigidity or stability to the fabric it is attached to. So, by definition you would come across interfacing on collars (well, inside!), waistbands, flaps of pockets, patch pockets and anything which is required to hold its form or structure. It comes in various weights. The one most requested for dressmaking garment patterns is the lightweight variant because rigidity is not required but structuring of a collar, or perhaps a waistband is preferential to maintain the shape of the garment. Interfacing comes in black or white versions so you simply choose the one that is most appropriate for the type and colour or your garment fabric.
So what about fusible? Fusible means that the interfacing has been embedded with droplets of glue on one side, this is what I call the ‘bobbly’ side of the fabric and this is what I call the wrong side of the interfacing. The bobbles of glue melt when the fabric is gently pressed with a warm iron between layers of fabric. (one should never iron directly onto interfacing as it will melt and stick onto the iron!). It will then stick onto the wrong side of the target fabric to provide structure.
Back in the day, I used to stitch interfacing by needle and thread before securing it to the fabric. Indeed tailors still do use this technique of stitching the interfacing in suiting to the suit fabric when they make bespoke suits, but let’s just be grateful for the wonders of modern technology allowing us to simply iron the interfacing to our fabric!
Thank goodness for Lightweight Fusible (iron-on) Interfacing….Hip, Hip, Hooray !!!
