They are fun and easy but take a little time. I made these to co-ordinate with our multicolored floral tablecloths. You could use school colors, holiday green & red or blue & gold, or all natural bone. I just happen to have several tins of old buttons from Mom, who used to make all our clothes when I was growing up. I recognize many of the buttons on these rings and it brings back happy memories when I am setting the table with them.
First, cut the number of rings you want out of waistband elastic, about 4.5" long for each. You can get the width that works for you. I happen to like the wider kind.
Sew on individual buttons, making sure to knot off each one. This will ensure they don't all come off when one invariably does. The flat buttons are easier to work with but use different kinds, shapes and colors for interest. Be aware that metal buttons tend to eat through the thread quicker so double sew those for stronger attachment.
After you attach the two ends together, finish sewing buttons over the seam and..volia!
I like being able to stretch the rings but, if you would like for the inside to be more finished, you could cut a strip of felt the size of the inside and glue it in after sewing.
