It is best to handle the edge of the fabric with the serger. Use narrow podrobnyi technicial or blanket stitch. If you do not have this feature on the sewing machine, then you can do without it. For example, the edge of the fabric to bend double for half an inch and carefully press podvorot. If the fabric does not give possibility at once to tuck the edge in this way, you can first wrap once, to stitch, then repeat the procedure.
Another way to handle edge - quilting with bias binding. To do this, take a strip width of approximately three centimeters. Its length should be several inches longer than the processing region of the tissue. First you need to cut off the excess fabric close to the stitching. Then you need to stitch along the crease line of short stitches. If the fabric is stretched, iron her iron. Then fold the fabric on the wrong side of so close yet rough cut, under the ACC put the edge gasket. Then put the line at the same distance from the edge.
In the processing of whimsical knitted fabric also has its complexity. Knitwear can be treated as piping, you can simple hem. To do this, lay a line one and a half inches from the edge of the fabric. Lead line should lead from the edge to the center. You need to ensure that the thread didn't pull the fabric, not scrunching it. Then tuck the edge and finish it with a serger .
Knitwear can also be treated rolikam. For this you need to stitch the cloth along the line, which will be skiving. Tuck the seam allowance and finish with a serger. The prepared strip of fabric (its width is two to three inches) fold in half in length. A little stretching, sew the front side to the front side of the product. Then attrocity on the front side, removing the binding.
Sometimes the model does not provide for the processing thread. Especially on these lightweight, translucent fabrics like organza and taffeta. In such case, you can try singe the edges with a lighter or candle.
You can also use a colorless nail Polish. He will not pour the fabric, reinforce the edges, and thus will not be visible even on white silk.
