After having invested countless hours reviewing our calculations, our Bias Skirt Calculator is now complete. You can use this guide (International Pleating Bias Skirt Guide Version 2) to calculate needed yardage when cutting pleated or non-pleated skirts, in addition to the yardage around the circumference at the hem of the skirt. This is extremely helpful when purchasing and applying trim to the hem. We hope you find this new tool useful and we are happy to answer any questions you may have concerning this new guide. We also welcome your comments.
