I found this frame in an Op-shop for $2! I knew it would look good around the photo of my great grandma Mrs Ohlsson. This particular photo is a copy of a copy - however it is my only copy and the only copy in Australia so I am treating it as an original. I can still use the frame from the op-shop - but I change the glass for conservation glass (99% uv blocking) and I change the backing for a rag board. Instead of using a mat board I have used plastic spacers to seperate the photo from the glass (to protect it from condensation and from getting stuck to the glass) before it's all sealed up with a tape on the back (to protect it from any unwanted critters).
When using a ready made frame it's very important to remember that these frames are made with acidic mat board and acidic backboards. Those materials + cheep glass pretty much creates a micro-environment for deterioration! Yes, that's right, a badly framed piece can deteriorate quicker then if you just kept the piece in a draw or under your bed. Something to keep in mind when heading to IKEA to buy frames next time. Not saying that a cheep poster need custom framing but it's important to know that any thing of value (personal or $) should not be put into a ready-made without appropriate changes.
