WCRS info page: This covers everything you'll need to know about having a wrap conversion ring sling (WCRS) made, including a calculator for wrap splits and explanations of all the questions and options I have on the ordering page.
WCRS order page: After you've read through and understood the above, you can place your order here. This is for any ring sling made with a finished wrap (that is, it's either hemmed or has good selvege edges).
Custom wrap hemming: For wrap chops (shortening a longer wrap), wrap splits between two customers where a sling and shorty or two shorties are being sent to separate addresses, hemming existing slings, and having scarves made from leftover pieces of an appropriate size.
Shoulder redos: If you have a sling whose fabric you like, but the shoulder style isn't for you, I may be able to take out the existing stitching and redo it. Most commercially-produced slings can be redone without losing significant length. However, if the sling was made by an amateur, the stitching may be too extensive, or the fabric inappropriate for a sling. Please email with photos before purchasing this option if your sling was not professionally sewn.
Custom slings: If you have unhemmed fabric -- NOT already-sewn wraps -- that you would like made into a sling, it's a custom sling. (WCRS have hemmed edges already, so I merely cut and sew; unhemmed fabric needs the edges hemmed, which takes me longer.)
In the future: Regulations concerning the testing of ring slings and wraps will be mandatory by the end of 2017. Similar regulations have gone into effect for mei tais and SSCs; these do not affect ring slings, so yes, you can still send your wrap to be converted :) This page explains what will happen as the regulatory deadline approaches.
