Suncatcher Eyes come with either plastic or metal washer backings.
If using fabric, cut a small hole for the eye stem.
Push the stem through your fabric (or crocheting/knitting).
Using the photo above as a guide, attach the washer to the stem on the other side of the fabric.
Squeeze eye and washer firmly to create a tight fit.
As always, if you have any questions at all, please feel free to contact me.
