Mono Monday : Corner

Totally amazed today by the revelation that Blipfoto has gone into liquidation. Comments on the blipfoto friends facebook page show how much affection people have for this community. I do hope it will be able to continue.
The first corner that came to mind for this week's MM challenge is here, the corner of one of my parchment craft perforating templates. Pricking through it with the tool shown  makes lovely patterns.
It also tends to make you cross-eyed.
