Watchpoint: You need to set up 2 pairs of fronts and backs – one for the left side of the body and one for the right.  So, technically, you’ll want to sew darts so that they’re on the inside of the side they’re on.  That’s easy to tell if you’re using a test fabric with a right and wrong side, but harder in plain muslin.  I’m a fan of adding a big X in pencil on the wrong side, so I don’t end up making two left legs.  So many years of sewing, and yes, I still need to save myself from myself…

    Great instructions! Good point on how to measure the crotch depth, that will help when fitting commercial patterns too.

    BTW, there may be a problem with the scaling of some of the pics – on my computer, the silhouette pics are displayed 2335 px tall…
