The women there taking classes were of varying ages. I was told that to become an expert, it would be perfect to attend school for two years. Because of the expense, I do not know what the tuition is, they try to squeeze all there is to learn into a one year course.
Just look at all those bobbins. The pattern is pinned onto a firm foam board covered with cloth. The placement of the bobbins then makes the pattern. Small pins are inserted into the foam board to "hold" the threads in place. Threads can be cotton or silk. I noticed that some of the very new beginners were using very thick thread. Probably a very good idea.
I purchased my first two bobbins. I liked the look of them. I can knit lace with two knitting needles, but I really can't imagine soooo many bobbins and keeping track of all of them and knowing when to move them. The teacher told me that once a week, children come to the classroom to be taught to keep the tradition going through the years. I think that is a wonderful idea.
No photos were allowed in the museum, but the highlight was a totally lace wedding dress that was many years old. The bride must have started as a toddler to get the dress done in time for her wedding. It was exquisite.
