2. Because your fabric can be expected to shrink when it is finished. you need to determine the woven dimensions required to get the finished dimensions you want. First enter the planned finished dimensions in the appropriate boxes. If you have calculated shrinkage already, those values will be prefilled. If you have not sampled, you’ll just have to enter an estimated value for the shrinkage percentage. Click the Calculate buttons to get the dimensions you should weave.

3. Now you can calculate the amount of warp you need. If you’ve used the previous calculators, the woven length and width are prefilled. Otherwise, enter those values. Also enter the amount of loom waste (unweavable warp, tie-on allowance, etc.) and sampling length, if any. We also need to know your epi, and how wide your sections are. Click calculate and you will get the total approximate value in yards (our calculations are rounded up, just to be safe), and also the number of spools and yards per spool.
