Would you like to learn how to paint a vintage window?  First things first, gather all your materials together in advance.  Many people ask me where I source the Victorian and Edwardian windows I use in our Vintage Windows Class.  Answer: anywhere I can find them.  Sadly with so many renovations being done, many of these beautiful windows are simply thrown in the skip. I ask friends to keep a look out for neighbours renovating, I look in salvage yards (there are a few on line), Vintage fairs and Ebay.  Do try to ensure the windows have no cracks BEFORE to buy them.
Other materials:-
Stencil - I just love them from Maison de Stencil
Acrylic Paint - any brand just as long as it is not too watery
Thin angled craft paint brush
small bowl to hold the acrylic paint
frog tape or similar tape (that does not leave behind residue)

Ensure your vintage window is very clean and you have removed any loose/chipping paint.  Tape the stencil into position.  Note that I am only using a small amount on the corners as the tape is only meant to stop the stencil from moving.  Do not over tape or you will struggle to remove the stencil, only blurring all your hard work.

Put a small amount of acrylic paint into your bowl - small amount because it dries very quickly.  Better to add more often than to have it all dry out in your bowl - and then also on your brush.

With a small amount of paint on your brush, start to paint.  Start at the top so you are not reaching over wet paint.  Paint from the corners outward.  It is important that you do not overload your brush with paint - to avoid bleeding under the stencil.  

Do take care where there may be delicate areas of your stencil and do not paint against these.  

Ensure you hold down any areas that are particularly delicate and also you may need to hold down the stencil in sections if the vintage glass is particularly wavy/uneven.

Do not try to get every last section of the stencil painted, if you have any difficulty, an outline will be fine as it is better to go back over with a fine paint brush to fill in some extra paint  - once the stencil is removed - rather than have paint bleed under the stencil.  Once you're happy with how the paint looks, gently and carefully pull back the stencil.  You can add gold or silver over the paint you have used.  I find gold/silver work better over a darker colour and not on their own.
