You would just need to make a suitable holder.

If you look below and left of Orion, there is a bright star. This is Sirius, which is the brightest stellar object in the sky. Actually, it's 2 stars orbiting each other wink
strictly speaking, the brightest stellar object would be our sun

Yeah but tape the stuff on in the cell you make or buy. Tape it and tape it again. Check and double check for holes.

Edit. On second thoughts, just don't do it. Project it.

Patrick Moore was always scathing of solar filters - but that was in books I was reading 40 years ago - and materials will have moved on since then.

I have one, bit hypocritical of me, but on an open forum I don't want people to think they can just wrap this stuff around the end and crack on. You need to be very very very safe.

My first attempt with Baader, it was a while ago and not imaged since as the conditions always trip me up. It was at the low point ish.

Meade used to make a dedicated solar binocular, if I remember right they were about £50, certainly under £100. The same performance as the filter but a more reliable solar 'seal'.

Aye, just saying be careful, very very careful as in you only have one set of peepers and get it wrong and you lose them.
