Double-sided heat and bond is used to join fabrics together. It is best used for joining small pieces of fabric to larger pieces.
Single-sided heat and bond on the other hand attaches only to one side. This type of heat and bond is commonly attached to fabric to make the fabric a bit more rigid.
Reasons Why You Might Need to Sew Through Heat and Bond
Generally, when you use heat and bond lite, you may have to sew through it. Since it contains a lower amount of adhesive, the fabrics can easily separate when you wash them or when they are ironed repeatedly.
You may also coat the thread and the needle with a lubricant. Liquid silicon is commonly used for this purpose. It makes your needle and thread slippery and prevents them from getting sticky.
