When preparing the sweater, you can press the seam as you normally do in the other projects
. This rule applies to the tissue that is normal and not too complicated. If you are sewing the fabric that is spongy and textured, then you should make an extra effort in terms of pressing the seam. Let's talk about ironing now.
If you are giving too much steam and heat to the tissues, then it can be completely flattened, but care must be taken to prevent burning. You don't have to iron the entire sweater, but only the seams. If you apply the iron to the entire sweater, it will be ruined and the fabric will distort. If you are going to stretch the ironing cloth, it will be extended throughout the project and the shape will be changed.
