Fiber Arts
As some of you might know, I periodically spend a week or two in the 16th century. Pensic is a camping event with 10,000 of your closest friends, and has activities suitable for all components of the SCA. Whether your inclination is to drink until dawn every night, or participate in field battles, you can do it. I'm inclined for the quieter pursuits: throwing axes, going to bardic circles, and teaching and attending classes. If you can't find things to do at Pensic, you are a very boring person. (I told this to someone who had complained about being bored...they did not take it kindly, but I do not withdraw the comment)
One problem with Pensic is that you meet so many interesting people doing so many fascinating things that you invariably come back with a long list of things you'd like to do, and many of us dive into various new projects after Pensic (heck, before Pensic too); with all due respect to those with legitimate medical issues, we refer to this tendency as "SCADD." For years, I've felt the draw to the dark side of the textile arts (excluding costuming). At Pensic 44, I gave in and bought a midsized inkle loom (which allows me to create up to 5 yards of band). At Pensic 45, symptoms further developed and I learned how to do bobbin lace.
