I could not find the thin double sided tape for the job ...
I bought thin, double-sided tape for my solar filter build at a CVS Pharmacy. It's the second largest pharmacy chain in the United States, with more than 7,000 stores.

I attached the filter assemble to a larger stop plate, also made of foam board, using velcro.
I often stop down my large dob with the black stop plate shown in this photo to improve its f/number when looking at planets or close double stars. The solar filter fits nicely over the 4" stop hole. With the 3" diameter solar filter in place, this dob becomes a f/24 unobstructed reflector.

Glad to know that you can get it at CVS or office supply stores. Kind of too late for me. I tried to buy it at building materials and Walmart stores, when the store clerks led me to this thick double sides tape.

I have built a couple of these filters for my C6 and AT72. Using the AT72 with my DBK21AU618 planetary camera I can fit about 2/3rds of the solar disk in the frame, made for a nice view during the Venus transit and solar eclipse last year.
