I haven't tried this yet for the Yo-SD, but if you have an MSD pattern just reduce it. Someone posted a chart to show how to reduce this, but I can't seem to find it. Try to reduce the msd patterns to 65% to get a Yo-sd pattern, but you would have to fit on the doll and adjust your sewing as you go.
Thanks bittersweetlove, but I have not Yo-sd... I want some pattern for sewing clothes for my friend. I try to reduce pattern for MSD. Thanks :grin:
