Tight

I'm joining in with Mystery Macro today. Thanks to osuzanna for announcing it under Challenges and in the Facebook Blipfoto Friends group. As a result, this time, I knew what was going on! :)

The trouble with tight cropping is that you may not be able to tell what it is. If this were genuinely abstract, I would turn it upside down- or at least sideways. The 'top' is too heavy. But since it is definitely a thing, I guess I better keep it upright. To be revealed tomorrow, as per instructions.
