The adjustable stitch holder is a versatile and easy method for securely holding live stitches when knitting. The stitch holder allows for using smaller materials, a locking fastener and string, that are portable and take little storage room. Adjusting the locking fastener to a specific measurement allows an item to be tried on, to be measured properly, or to determine if the shape is correct. Because the string has little to no memory, the ends, regardless of length, will hang not pulling or distorting the knit material. In addition, the flexible string allows an item to be laid flat for measuring making the measurement more accurate. Further, stitches or knitted items have little chance of being damaged by the stitch holder and the stitch holder will conform to the knit item instead of being forced into a shape.
