Pipeway

We have a tea strainer that fits in the teapot.  It's become a bit bunged up over the years (stick with me, there is a point!) and Sharon's been cleaning it with a pin. She's most of the way there but there's still a ring left in the middle.  I noticed that it was about the same size as my compact camera lens, so took a photo through it.  Then messed with it in Photoshop...
