There are thousands of members on Gransnet, having dozens of different conversations simultaneously. Each subject has its own words. Explaining every term used in every post gets tedious for the poster and boring for the readers.
I am currently doing some patchwork which involves creating log cabin blocks which will have sashing, all set on point with setting triangles and a pieced border with mitred corners. I will of course need batting. I have enough in my stash not to have needed to buy fat quarters. I shan't be doing any applique or reverse trapunto on this, or using fusibles, but may do some quilting in the ditch. All sewing requires attention to grain and nap, that goes without saying, and there will be lots of basting involved.
Those who do patchwork will now have a mental picture of me working away at this and know exactly what I am doing. Those who found my account interesting will find out what the **** I am talking about by asking or searching. Those who can't be ***** will move on to somewhere else.
Those who can't sew a stitch and want to learn will go to a class to learn how to. They won't expect me to give them a master-class for every word I use. That just slows down conversation.
If you genuinely do not understand the concepts that are being discussed, soontobe then your best course is to find an evening class in the subject that puzzles you. If you do understand (I remember commenting in a previous thread that your confidence and knowledge seemed to have increased vastly since you joined, to which you replied that you were never as naive and ignorant as you were assumed to be, but went along with it) then stop flannelling.
