As always, a lovely morning at Emsworth. Showery weather and a popular sporting event conspired to keep people away in their droves, but it was all good fun, and a chance to catch up with fellow stall-holders. Actual sales were few, but I did receive a commission to make two lamp holders based on the shape and size of one of the large garden pots, and I shall enjoy making them. One of the sales was the mug referred to in an earlier post. The purchaser recognised the formula – Emsworthians are smarter than Wodehouse would have you believe, although Jeeves might well have known the basics of differential calculus.
