The sewing police will only come after you if there is that tag somewhere visible… you know, the kind like you see on mattresses and sofa cushions? Yeah. If you don’t see one of those, you *should* be okay. tehehe
I’m only answering this one because it was a topic of discussion at the Vermont Weekend Sewing. Heather Ross was instructing on how to insert a sleeve – (which you know I love you, Heather – a lot!, but Liesl’s method is… well…. easier – smooches, HR!!)
I remember Liesl saying (correct me if I’m wrong, Liesl) that one of the main reasons she has you set the sleeve ‘flat’ is simply because of the itty bitty arms on children’s clothing. Adult sleeves are usually set in the round because there is more room to actually get the seam under the needle. My free-arm is very, very tiny so I don’t have an issue usually with setting in the round, but I still prefer the flat if I can do it.
There may be other technical issues as to why and if there is, Liesl, please teach us. We are your pupils!
