How to bond the fusible cotton with cloth?
Ironing position should be gradually spread from the middle to the edge around the way. Before that cannot adopt the method of sliding, which should be “step by step” pressing. After ironing, you can move until the cloth and the lining are cooled before proceeding to the next step.
Because the cotton layer is thicker, the heat transfer will be hindered. Put the interfacing fabric under the cloth to press with iron will be better. For some auxiliary cotton without a seam (smaller than cloth around a circle), as it is difficult to aim at position, then we could start turning and let auxiliary cotton to be slightly adhesive, then turn it over and iron to be bonding formally.
Should use steam or not
This is a controversial issue. In fact, some adhesive lining is easier to adhere under certain humidity conditions, the fusible interlining with dotted coating used steam usually, so does double sided fusible interfacing.
If you have no confidence in your own method of adhesion, you can use some edges or pieces to test it. If the bonding effect is not strong, it is caused by too low temperature or too little pressure and too short a time. If the fabric is bubbling, in addition to these reasons, maybe there is a gap when ironing.
What should you do if the lining fused in the wrong place? This time you can heat it with the iron and peel it off while it is hot.
