Pin weaving. Pin weaving is a form of small-scale weaving traditionally done on a frame made of pins; the warp and weft are wrapped around the pins. Pin-woven textiles have a selvage edge all the way around.

Pin looms were popular from the 1930s to the 1960s. Quite elaborate patterns were published, especially in the 1930s. 

21st-century designs often focus more on the fiber than on elaborate patterning; for instance, yarns with precisely repeating colours can be used to make plaids.

Equipment
The equipment needed is minimal, consisting of pins, a pinnable board, and a bodkin needle. It can also be done on some types of knitting frame. There are also commercial looms made for pin weaving. Smooth, rounded pin tops are desirable; they don't snag the yarn or fingers. Pins are usually spaced ¼ to ⅛ of an inch apart (3-7 millimeters apart). The pins may be numbered (with numbers written beside the pins), and the lower-left corner may be marked, for ease of reference when working patterns. Ideally, the background should contrast with the threads.

Weaves
For plain tabby weaves, only every other thread in one direction (a quarter of the yarns) is inserted over-and-under with a needle. The others are wrapped in layers; first the odd warps, then the odd counterwarps (at 90 degrees to the warp threads), then the even warp threads. The counterwarps thus pass alternately over and under the warps, but they do it in parallel, passing over and under in unison. A weft thread is woven between each pair of counterwarps, passing under where the flanking counterwarps pass over, and vice-versa. 

This timesaving method cannot be used for more complex weaves, such as twills. For these, the odd warps are warped, then the even warps are warped (giving the edge loops), and then the weft is woven with the needle. There is no counterwarp.

Joining and edging
Pin-woven textiles are small, and are often stitched together into larger textiles; the finished product has visible seams. Joining methods including whip stitch, cross stitch, running stitch, back stitch; overcast stitch is fast but tends to pucker. In crochet, crocheted slip stitch and single crochet are used, as are knitted 3-needle bind-offs.

Patterns

Many sewing patterns designed for pinweaving use rectangular construction, with all seams lying on selvage edges. This eliminates waste. Others use non-rectangular construction, cutting curve-edged pattern pieces out of a piece of cloth formed by sewing together the squares. Garments can be cut on the bias or on the grain with similar amounts of waste.

Seams joing the squares may be eased; that is, there are more squares on one side of the join than on the other. The extra length is distributed evenly along the seam, creating fullness without discrete pleats.

Similar methods

Darning looms are similar to pin weaving, but instead of being wrapped around pins, three of the selvages are stitched into the cloth being repaired. The fourth is wrapped around a revolving-hood mechanism which, when rotated, forms a shed and countershed, making plain tabby weaves much faster. When finished, the hooks are removed, and the fourth selvage is usually stitched to the cloth.
