Hellooo!!!  I'm breaking my blog silence(!) to tell you about a weekend which went completely not according to plan, but in a very good  way.
I started off well, with a gathering of knitters and spinners on Friday  evening.  One of the members mentioned she was in search of an all-wood  drop spindle to use on the plane back to the states, so I said she could have  one of mine:
I arranged to meet her at the knitting in public day on Saturday, to  hand it over  This was my first unplanned event; I'd thought I'd be going to a different location, if any.  So I packaged the wee spindle up with a sparkly batt for  good luck, and off I went.  I was there for less than two hours, but had  an awesome time.  (I also learnt that I should carry my business  cards with me whenever I go anywhere with either knitting OR spindles in public!)
I had so much fun I decided that I really did want to go to one of the 
Open Farm Sunday events in our area, to demonstrate spinning.
So on Sunday morning, I made seven more spindles, packed up samples  of handspun yarn and things made from it, some food and water, my   wheel and a spindle, and trucked off to 
Burwash Manor (eventually.  I had a  bit of a disagreement with the GPS on the way...).
And I'm so glad I  went!  No-one else from the group made it to that event, so I had the stand all to myself.  Which, in a way, was nice; I felt fine handing out my business cards (which I remembered this time!), and there were no odd  little decisions to make as to who is the 'group leader' and who should  be talking to whom or anything like that.  I'm very glad I took all  those samples, though; if I'd assumed someone else was going to  be organising it, and just turned up with myself and a wheel, it would  have been pretty lame.  If I'd known, I'd have taken even more!
Overall, I had an absolute blast.  I spent most of the time spindling, and gave away four spindles.  One went  to a little girl who was an absolute natural; one went to a lady who has  always wanted to learn.  I helped children too young to try spindling to make hand-twisted woolly bracelets, and let several children treadle  the wheel (and was glad I had a double treadle wheel; it's definitely easier to get the hang of).  There was a group including several special needs children  there; one boy in particular loved treadling.  He came back  several times during the day, and sat and treadled industriously, with  an aura of calm radiating from him.  It seemed to be enough, just to  press the treadles and watch the wheel go round.
I also tried spinning wool whilst a child treadled.  I only did it once,  at the end of the day, and it helped that the wee lad was very  consistent in his treadling (and didn't just want to make the wheel go  as fast as possible!).  I was able to spin a short length of yarn which  could be plied back on itself and taken as a souvenir.  I'd definitely  do that again, with children who can treadle well enough.
I also played the "what colour next?" game with a group of children who were  watching me spin on the wheel.  I've found in the past that it's not always  obvious that the fluff in my hands is being converted into a yarn which  is being wound onto the bobbin; you can't really see the yarn moving.   So I had small scraps of coloured fluff and asked them to pick the next  colour.  They could see each colour get spun up and move onto the  bobbin, and I eventually pulled off the multicoloured single and plyed  it back on itself.  Two people asked if they could have a scrap to add  to a 'memory stick' - not the computer kind!  These were something new to me, and I thought they were a brilliant idea.  I think there must have been a craft tent where people were making these  during the day.  A memory stick in this case was a sturdy stick, about a foot long.  It had a string wrapped snugly round it in a  spiral, about one turn per inch, I'd guess, and tied at each end.  Bits of 'stuff' (feathers, straw, wool  from the sheep that were being sheared, and my yarn too!) could be stuck  behind the straw to make a sort of sculptural collage of the day's  mementos.  The fact that my demo yarn was actually asked for really meant a lot to me.
I met kindred spirits, and the merely curious.  I explained wheel  mechanics, and talked about the sheer number of hours needed to provide  yarn for a household before the industrial revolution.  I compared the per-minute efficiency of spinning on a wheel with the per-week efficiency of spinning on a spindle, which can go everywhere with you.
Unfortunately, I  also managed to trip on a totally flat piece of ground at the end of  the day, and do a real number on one of my knees.  I left my business  card for the lady organiser, who kept coming round with cups of tea  (thankyouthankyouthankyou!) and cake (omnomnomnom!), so with any luck I  may hear from them again in the future.
So, what did I learn?
-  That I can pull off a one-woman spinning demo at virtually zero notice.
 
-  That I could easily have more materials: samples, leaflets, all kinds of  things, ready for the future.
 
-  That the gift of a simple spindle can reduce children and adults to  incoherent joy.
 
- That I (still) love doing demos, and I should be aware of opportunities  to do more.
 
- That, really, I ought to remember to use my camera.  D'oh!
