I’ve had an easy time being focused lately. I say no to obligations or opportunities that I would have easily accepted before. I have fewer things on my todo list, which means I get to spend more time on the few things that I’ve said yes to when I sit down to be creative. I also have a stronger sense of my values …

It has been a very long time since I’ve dealt with a major loom screw up. A really long time. Like I don’t remember the last time? And it isn’t because I’m so very good at this whole weaving thing, but it sort of is. I’ve been weaving since the mid 70’s. If there is a mistake, or screw up, I can assure you I made it…

How I lost control of our bank accounts to a phone scammer
Yesterday, instead of having a productive afternoon at home, I had the privilege of sitting at the bank for a couple of hours, resolving a problem completely of my own doing: I fell for a phone scammer.
