The number one cause. When a pattern includes an acute angle (less than 30 degrees) at the point of a dart or a V-neck intersection, the stress has no path to dissipate. Instead, all the tension concentrates at the tip of the stitching. Within a few wears, the fabric tears precisely at that point.
Instead of risking your computer's security, you can use the official free options provided by the developers: rayon design crack
: Rayon must be properly scoured and pre-treated to ensure uniform absorbency; failing to do so can lead to "color paste dry crack". Prevention The number one cause
: The document outlines specific load cases and calculated design loads used to perform a "crack check," ensuring the structure can withstand seismic or environmental pressures without exceeding permissible crack widths How to Access the Full Paper Within a few wears, the fabric tears precisely at that point
Don't wash samples on delicate. Wash them on "normal/cotton" hot cycle with a heavy towel (to add abrasion). Dry on high heat. Do this five times. If a crack appears, your design fails.
Use narrow seam allowances (3/8 inch instead of 5/8 inch) to reduce bulk. More importantly, finish seams with a clean, flat method like a turn-and-stitch or a bound seam, rather than a bulky overlocked serger edge, which can create abrasive ridges inside the garment.
