Woven Backrest Office Chair
The following are the key points about the woven backrest office chair:

Woven Heart-shaped Chair Backrest Techniques
When weaving the heart-shaped backrest of a chair, after completing the non-increasing and non-decreasing part of the weaving, when there is half a length of yarn left at each end of the cushion, a needle-splitting operation is required. Specifically, divide all the loops on the knitting needle evenly into two parts. If two pairs of knitting needles are used, there is no need to thread the loops on the left-hand side with a yarn string. After confirming that the number of stitches on both sides is the same, tie a knot to prevent the loops from falling off. Then, continue weaving from the right-hand side. Subsequent steps will involve weaving multiple rows with different colored yarns and decreasing stitches. Through these steps, gradually complete the weaving of the backrest to give it a unique heart shape.
Relationship Between the Weaving of Executive Chair Cushions and Backrests
When weaving the cushions and backrest covers of executive chairs, in terms of materials, a total of eight skeins of yarn and two liang of combined yarn are required, and the woven width is approximately fifty centimeters. Regarding casting on, usually forty stitches are cast on, but the length can be adjusted according to personal needs. When finishing, reserve two meters of yarn for sewing. When sewing, operate with the reserved yarn and tie a piece of yarn at the bottom in the middle. Also, reserve at least ten or twelve meters of yarn in advance before starting to weave. The casting-on method can be two-handed casting-on, etc. Although this tutorial is mainly for cushions, the weaving of backrest covers and cushions has similarities in material selection, casting-on and finishing, and other basic operations, so they can be used for mutual reference.
