The Bernina electric sewing machine was another.
One remembers the day it arrived. One was nine. The machine is 45 years old. It still starts first time and purrs out an even stitch with excellent tension.
See how it is knitted in the round.
See how there are no arm holes.
See how the neck hole is tiny.
That would be SEWING - preferably on a sewing machine.
Now it might seem that because One has three published tea cosy books that designing a Fair Isle Vest would be a sinch for One.
Tea cosy design is EASY by comparison. Oh yes it is.
One followed the fair isle patterns from graphs found in books....
But One measured and counted and finally found a purpose for all those nasty high school years filled with ALGEBRA.
Not that One remembered HOW to do algebra but One did have a light bulb moment as to WHY One should have remembered algebra.
But One got there with a little help from The Bloke whose algebra has stuck. Ta Jules. You're a keeper.
