These are sort of technical AND artistic questions:
Do you always use the same size picots?
What size picot do you consider optimum for joins? Do you make different size picots for joins than for ornament?
Does the size of the thread have anything to do with size of the picots, either absolutely (x mm or 1/x in) or relatively (a picot the size of 2 DS) ?
How much does the number of DS between picots affect the optimum size of the picots?
Do you ever make a pattern and omit the decorative picots?
Do you use a picot gauge? flat, round, vertically, horizontally?
Can you guess that I am fussing with a pattern and the picots are driving me crazy~~~~~~~?
