Mammillaria plumosa

This is a close up of one of my cacti. It was harder than I thought, because there seemed to be all kinds of debris caught in the spines that I didn't notice to begin with.

This is my 21st image, so I've managed 3 whole weeks, and I'm really impressed how this has worked for so many others... not missing a single day. I'm going to aim for a year now. The discipline has worked. I've had my camera out more, and tried things I hadn't previously. And if the image doesn't work out first time, I just have to have another go!
