Hmm, if I am putting a row of fabric, that is all different fabrics, around each tshirt block , then putting sashing of all the same fabric between all the blocks, what is the first row of fabric I add called? Is it still sashing? Is it trim? Edging?
Is sashing only when it ties the whole top together? Borders go around the unit... or am I adding a border to each square?
Sometimes it really matters what things are called when trying to explain what one is doing and plans to do.
