I painted 'mod podge' around the rim to hold the material in place
around the hoop.
I didn't get too close to the circle that will show,
just in case the glue might show through.
After weighting down until the glue dried (with a heavy book),
I clipped the material very close around the inside of the hoop.
A favourite old, unrepairable bag.
My beautiful ~ torn ~ repurposed silk sari skirt.
As is often the case, I did no research and just 'gave it a go'.
But I think the result is actually quite effective!
