Buttonholes are serged, obecnie, air, loops of rolica or woven cord and telemetrie.
 

 Overlock loop (Fig. 55) are applied to things of a light and thin fabric, in the women's, children's and men's products, and in linen. Loop size is determined by the diameter of the buttons plus 3 - 5 mm for the free passage of buttons. Execute a blanket stitch loops in the following way. On both sides of the intended line of the loop at a distance of 2 mm will do the small stitches seam "forward needle" thread, which is designed to handle loop.The inside seam along the intended line of the cut straight hole, the hole edges ormative circle overlock seam, then one side of the hole will process the looped seam at the end of the cut make a clip of several linking the thread just keeps, we will process the looped suture and a second side hole in the end of the second edge of the cut formed by the hook up. In the processing loop of the buttonhole seam the needle and thread to stick outside seam "forward needle".

 Obecnie loop (Fig. 56) used for products made of thick fabric (coat, jackets etc.). Are obecnie loop in the following way. The distance from the edge of the Board to the hinges measure out the size of the diameter of the buttons. On the front side of the product laid a piece of cloth - a rectangle with length 5 cm and width 3 cm from a fabric of the product. Rectangle tack face-to-face fabric. In the center of the rectangle is the proposed line of the loop depending on the size of the button. On both sides of the intended line measure out 3 - 4 mm and promotive another rectangle of such size that it fits the button edge.Around a new small rectangle, stitch one or two times depending on the flowability of the fabric, remove the basting thread through the loop through the hole, not reaching the end of the loop is 0.8 - 1 cm, and make the notch in each corner of the small rectangle. Continue the loop to turn out on the wrong side, the seams lay in opposite directions so that the front side of the buttonhole to release the edge equal to half
the width of the loop. Both Kant loop between smetimes on the front side, outlive and fasten podborom, which make the cut according to the size of the loop. Cut edge of holes podborta bends inward and filed concealed stitches. 

 Air loop (Fig. 57) are used in products from fine fabrics for the buttons of small size, in children's products, products with a closed collar, as well as in places where it is impossible to penetrate and impossible to sew the metal loop for the hook.

Air loop the following way. A needle and thread to stick inside the fold edges so that the knot stayed inside, pulls a needle on the front side of the edge again and inject the needle from the front to purl, leaving between the two punctures, the distance of the size of the buttons. Thus we extend the thread inside the fold of the fabric several times. The outer threads are left not strained, but slightly concave in the form of an arc. The resulting loop is processed looped seam so that the stitches were close to each other.

 Loop of rolica (Fig. 58) are used in dresses, blouses, jackets and other products depending on the style and fashion. Rolikovye loops are made of piping of the same fabric or fabric finishing color. Rulik, scribbling on a piece in an oblique direction and then cut, leaving at the end of the line for the funnel of the extrusion. Rolikovye sew loops in the edge of the item in the following way. Pieces ready rolica laid in the edge of the clasp on the size of the buttons on the front side so that the arc of the loop to the inside.Closed loop binding (plating edge), tack, stitch, fold bake on the reverse and on the edge of the item to be processed according to the style, bake and sew a hidden seam.

Such loops can be performed from the finished braided cord. 

 Sewing buttons. Buttons are sewn in different ways depending on the purpose. If you need a tight fastening (coats, jackets made of thick fabric), then a button is sewn firmly with a few stitches. To form a stem under the button, between the stitches laid a match, and they are free. Removing a match, the stitching wrap a few turns of thread. 

In the products of thin fabric on the wrong side under the button, puts a piece of cloth.

The decorative button so as not to wrinkle the fabric, easily sew a few stitches.
