B is for Bag Out
V. to bag out, bagging out, bagged out
Bagging out if a phrase you will come across quite often. It simply means stitching pieces right sides together then when you turn them through the right way the seam allowance is trapped between the 2 pieces on the inside so you get a neat finish on your garment.
Lots of different pieces can require bagging out, and can either be partially bagged out or fully bagged out.
For example something like a strap or a belt would be fully bagged out along all edges then attached to the garment.
Whereas a neck will only be bagged out along the neck edge with a facing and then the bottom edge of the facing could be either attached to a lining or finished separately, with a binding for example.
Linings are another piece that is bagged out. If a lining is fully bagged out it means there is no access between the outer and the lining, so you can't see any unfinished edges, it all looks perfectly finished on the inside.
Zips are often bagged out either with lining or with a facing. The zip ends up sandwiched between the inside of the garment and the outer so its completely clean from both sides and you can't see the zip tape.
