Update. I'm halfway through blocking my eight lone-star diamond arms. Some are going worse than others. I am following closely S. Shambers (?) video instructions.
One of the things she does not cover is how much of a difference can you have before you cannot use the blocking/starching method to "shrink" a piece.
I have tried very hard to get the shrinking results she demonstrated, but it's not going well. many puckers (although they ARE starched to hell and back.)
