Once you have chosen your yarns, you will also need to determine the sett of your cloth, or how many threads per inch the fabric will be. If your pattern does not give you this information, or you are using an alternate yarn or are creating your own design, wrap the yarn around a ruler, so that each wrap of the yarn is just touching. Wrap the yarn over a space of 1 inch. Then count the number of wraps. This will give you an approximate sett.
