I agree with Etana - go with the heavy-duty pant/skirt style hooks & eyes. And I wouldn't do the tie-back o-ring thing with a coin bra -- it will have the tendency to droop in the front on you from the weight & that would be bad.

Hi Etana, and others...

I feared the eyelet might not be sturdy enough. I have seen them in sturdier fabrics than pleather--I believe they also sell them in webbed cotton. Upon researching on the internet it looks like the most I would get is 2 sets of eyelet within the width of the strap. Oh well.

(Quote from Etana's post): I'd suggest reinforcing the existing strap and *firmly* attach heavy duty flat pant/skirt hooks. (end quote)

Do you have any recommendations on good heavy duty pant hooks?

Hi Faedra,

This will sound silly. I saw O-rings at my local Joannes that didn't look very sturdy (I think they were called Glamor rings?) . Are there are particular kind that are better than others?

For a back-closure, I took the base material that I used to cover the cups and made 'sleeve's' with hook 'n eye closure. On the 'cup end', each sleeve was as wide as, and secured to the cup. with reinforced stitching. The 2 sleeves were 2 inches longer than the 2 back straps and gradually narrowed from the cup to the closure. To put the bra on, the sleeves were pushed towards the cup to expose the strap/closure for easy fastening. Once fthe bra was fastened, the sleeves were drawn towards each other and fastened with hook 'n eyes. The extra sleeve length was distributed evenly across the back strap for a slightly gathered or ruched' look. The great thing about the sleeves is how easy it is to get in and out of and that the elastic backstrap can give/stretch with your movement. I did not feel as 'bound' . I felt secure but comfortable.
The bra was sturdy and secure enough to be covered with the real coins my dear grandfather drilled for me.
