Craf-Tex - Midweight Interfacing
After much fussing and testing, this is THE product I love for interfacing the body of handbags. A non woven sew-in it is just the right weight for many of the bags I've been making recently (3 handbag patterns are coming up in the months ahead). Even though it is called 'lite', it really is a good basic mid weight with many uses. The label SAYS light, but it is actually a good basic mid weight.
The companion product (I recommend you keep both on hand), is Craf-Tex heavy, which is perfect for the bottom of a tote-type bag.
