First, find a scrap of black t-shirt material. If you don't have some lying around, you can cut the sleeves off a black tee from your closet or a thrift store. (I suggest the sleeves because then you'll still have a wearable shirt.) Figure out what side of the material you want to be the outward-facing side. T-shirt material rolls up, and if you put the rolls on the outside, your ring will have a nice 3-D effect. Remember to sew on the "wrong" side of your fabric, because you will be turning the ring inside-out later.
Steps shown in the picture:
- Cut out a small strip of fabric that is slightly longer than the circumference of your finger. This is as scientific as we're getting here.
- Wrap the fabric around your finger and when you get a good fit, pin the two ends together.
- Take out the pin and sew over the area, either by hand or with a machine. It doesn't need to be perfect. I sewed mine crookedly with white thread and the finished product still looked fine!
- Cut off the ends and turn the ring inside-out. You could iron the ends flat, but as I wore the ring, the ends got pressed down flat anyway.
The only problem with a fabric ring is that it'll get soggy if you wash your hands with it on. But the stretchy material will help accommodate finger size fluctuations (don't tell me I'm the only person who has that), and if it gets lost, who cares? From one t-shirt sleeve you could make at least 20 more.
