Machine stitching should be smooth, without gaps, with evenly pulled thread stitches. Flatlock slices sour cream components perform under smachivaniya on the workpiece side (opposite side from seam). The ends of the inner lines reinforce the reverse stitch length of 0.7 - 1 cm Ends of the finishing lines fixed reverse machine stitch length 0.5 - 1 cm or tied to the underside of the knot (in Atelier of higher rank). The ends of the closed lines have to go to one another for a length not less than 1.5 - 2 cm (on the operations vrachevanie sleeveless, podseleniya the bottom of the skirt and so p.).
Cut parts overcast cotton, synthetic threads or yarns.

Performing wet-heat works

the appearance of the product depends on the quality of the wet-heat treatment, so proper execution is critical.
Wet-heat-treatment performed with irons, steam and electric presses, and steam-air dummies.
When performing wet-thermal papers must adhere to the following rules.
1. Details pre-moistened or steamed, and then iron to remove moisture.
2. Before razotajiem seam must be ironed from both sides, satwiwa fit.
3. When razoruzhenie joints achieve a tight fit of the seam allowances to detail.
4. Wet-heat treatment on the reverse side operates without proteinlike, and from the front side through protohellenic.
5. Wet-heat treatment of iron products are mainly from the wrong side and press from the front side.
6. Wet-heat treatment of boundary areas of the parts (sides, collar, hem etc.) from the tissues on which there are traces wyotech lines after the adhesive is recommended in two steps: first priorivet with little moisture or without, and then (after removal of the temporary fixing threads) repeated Ironing treatment with essential moisturizing components.
7. Lasy (Shine), the resulting wet-heat works on the front side parts, can be removed by using Stripping.
8. When the wet-heat processing of light materials for Ironing tables or presses a pillow cover with a light cloth.
9. After the final wet-heat processing, the product must be dried in a suspended form to complete fixing the given form.
The basic parameters of the wet-heat treatment are: temperature, pressing force, processing time and moisture (tab. 4).
