The sizes of the paintings
A6 is like a small photo or a postcard. These paintings are often used on folded cards. And they are easy to put in a small frame, so you have a unique gift that isn’t too expensive.
A5 and bigger paintings will often not be used on a folded card. These paintings are often framed or put up on a matching contrasting piece of cardboard. Framing the artwork ads a whole new dimension and often you can easily buy frames quite cheap.
Be aware that the wax painting doesn’t touch the glass and use a passe-partout. Also never put wax paintings in the sun or behind the window. The beeswax will melt at temperatures above 60 degrees Celsius and will become soft earlier, like a candle.
