SWITCH TO DIGITAL TAILORING
It will save you and your customer a lot of time and hassle. And probably money too.
The process is completely remote and do it yourself. Your customer uploads a scan or pictures and I do the magic. All you have to do is to send a link to your customer and to make sure that the garment is made somehow.
Within a few days you will have a ready-made pattern at your disposal. Digital or on old skool paper. Depending on your wishes and way of working, the output can be customized to your needs.
