I finally got around to cleaning and painting some old pictures frames I had. These were a mix of charity shop finds and old neglected frames I had.
The first thing to do is take them completely apart, remove the back, the glass etc. I wash the glass in a bowl of washing up liquid (carefully) and leave it to air dry.
I love this grey colour, its Homebase Sanctuary range, "shadow" colour in matt. Here's a link to some of the "before" pics. http://www.mariahomedecorations.com/2012/05/charity-shop-finds-vintage-childrens.html
I cleaned up some destined for photos so it doesn't have to be just children's pictures you can do this for.
Hope the sun stays out, have a great day,
