Standard width for a ring sling is between 26"-32"
If the mesh you bought is 60" wide, the easiest option is to simply cut it down the middle. Use the holes in the mesh as a guideline for cutting a straight line.
At this point, if you want, you may be able to use the mesh without rings as a "shorty wrap," depending on how much fabric you bought and what your
base size is. If you are between a base 5-8 and bought 3 yards of fabric, you likely have enough to use it for a
traditional sling carry.
If you want to use rings, keep in mind that mesh is too slippery for a
no-sew ring sling, so you will need to sew your rings in.
