Sizing For Hemming And Shrinkage
We have a full Cut & Sew service here at Contrado, and are able to hem your fabric prints for a small additional charge. We create a small one- or two-fold hem that typically uses 0.2" to 0.75" (5-20mm) of material, depending on the thickness of the fabric. So, for example, if you want a finished piece of fabric that measures 39.37" x 39.37", you will need to order a size of 39.96" x 39.96" to allow for the hem (on top of that please also allow for shrinkage of min 2%). The thicker the fabric, the bigger the hem will be. You can choose to have your prints hemmed with either Black or White thread. On our silk and other light woven fabrics, one hemmed edge will be straight (vertically down the roll) and the other will be slightly rippled. The hemming material allowances are as follows and you need to make your print bigger to accommodate the hem:
- Light Fabrics (0.59oz-2.95oz): For silks and other light fabrics, we use 0.24" - 0.32" / 6mm-8mm in the hem (2 fold), so overall width/height will be minus 0.48"-0.56""/ 12-16mm
- Medium Fabrics (2.98oz-5.90oz): For medium-weight fabrics that fray, we use 0.5 - 0.75" / 15-20mm in the hem (2 fold) so overall width/height will be minus 1.4" - 1.6" / 35-40mm
- Stiff/Heavy/No-fray fabrics: we use 0.5 - 0.75" / 15-20mm in the hem (1 fold) so overall width/height will be minus 1.5" / 35-40mm
All of these measurements are approximate and can vary. Including with shrinkage, it can mean a fairly significant difference to ordered dimensions, so please plan your print accordingly. Depending on how open the weave is, our fabric can shrink anywhere from 2% to 8% with the average being 2.5%.
