A friend of mine would like a stained glass window with a bespoke design at the top of her stairs to replace the existing window. Real stained glass would be too expensive, even if I was capable and were to have a go myself, so I was thinking of making it with adhesive lead strip and glass paints on a clear "plastic" sheet and then fixing this on the inside of the existing glass. I've seen a few links on t'internet for this kind of thing but have a few questions.
The existing window is a double glazed unit approx 500 mm x 1200 mm.
1 I'm confused re the different materials and what would be best for this. Polycarb? Acrylic?
2 Would 2 mm thickness be OK?
3 Whats the best method for cutting a sheet to the exact size of the existing glass? Score & snap?
4 I was thinking of fixing it to the existing glass by making it a few mm smaller all round and then using a narrow silicone bead to hold it in place. Any other ideas?
5 If I fix it rigidly in place as above, what about differential expansion? Would it buckle?
Grateful for any advice.
Cheers

Well - if you must..... grin - I work in 'real' stained-glass..

DECRA Led used to be the people who make this stuff, but they got taken
over - you could look at http://www.decraled.co.uk/

The double-glazing companies use the self-adhesive 'lead-on-a-roll' and
self-adhesive coloured vinyl sheet.

There are also glass paints (Pebeo) - which can produce a similar effect.

I'd imagine you'd need a base that wouldn't bend - possibly bog-standard
4mm glass would be best - and there are 'secondary glazing' systems that
would allow you to mount the glass relatively safely.

Depending on where the thing is to be fitted - you may need to consider
using toughened glass.

You may also end up getting condensation trapped between window and your
stained glass sheet.

Any reason why you couldn't do it on the actual glass?

Sorry if I have offended any "real" stained glass crafts people out there! Cost is just too prohibitive, as well as my expertise as a first timer (although I have cut window glass many times). Thanks for the links to suppliers of materials.
As I said my first thought was to use a sheet of polycarb/acrylic but I don't suppose there is any reason why I shouldn't use a piece of ordinary window glass as you suggest. This would probably get over any differential expansion problems. I intend to fit it so that there is no gap between it and the internal glass of the double glazed unit to avoid condensation problems.
The window bottom is about 4ft high on the landing at the top of the stairs, so I would not envisage any safety problems.
Thanks again.

None, other than working from a pair of steps or similar on a vertical surface. I thought it would be easier to draw and paint the freehand design on a horizontal surface and then fix it in place when we were happy with it.

Not offended at all - only kidding!
I seem to recall that there were secondary d/g systems that used acrylic
sheet - possibly 2mm...

You won't get a perfect seal between the existing glass and the new
'stained-glass' panel - you will get condensation.
The way I do it with stained-glass panels, which are often fitted as
'tertiary' glazing, is to deliberately ensure an air-flow between the
stained-glass panel and the existing d/g panes - simply be allowing one
or two small gaps at top and bottom where the stained-glass framing
meets the double-glazing frame.

There are a lot of folks who make double-glazed units using the stick-on
lead on one of the glass sheets - you might find it cost-effective to
get one of these companies to make you a single sheet of glass (rather
than a d/g unit) but with the lead and plastic film already applied..

Another way to introduce the colour is with acrylic paints - Pebeo are
the well-known supplier. These paints need to be 'flooded' into the area
- but if you're using the stick-on lead then you could do that..

Simple timber 'picture-framing' profiles can be used to secure glass
panels to existing window-frames...

2mm acrylic is warped before differential expansion, never mind after. Use 4mm if you want it flat.
Plastics don't last, it makes more sense to use glass.

One other thing. If the houses in a conservation area, then alterations like
this could be an issue, but then if its already upvc, then I'd imagine there
is no problem. Most of the ones I have seen are between the panes in a
double glazed unit using the vinyl method mentioned in this thread.
Cheap ones can go rather yellow or peel so be careful. Same goes for the
fake leaded pane windows.
Another thing is that it can make the area seem very dark in day time.

Also, glass paints used to be solvent based, so quite possibly
incompatible with polycarbonate or acrylic.

Is that one actually transparent though? In my first house (Victorian),
the inner front door had plain glass but I was able to buy a suitable
fake stained glass pattern. Not expensive, and looked fine from the
other end of the hall.

Thanks to all for comments and suggestions. Ill let you know how I get on. May be some time - as I mentioned it's a bespoke design by my friend and she hasn't drawn it yet!
