I mean - what seamstress in her right mind doesn't want their three year old to fling up her hands and say 'let me eat cake!' ?
I have, for some time, itched to learn how to draft a sloper for a child. Winifred Aldrich's excellent book set me on the road but she just tells you what to do and not why. LiEr's series didn't so much fill in the gaps as become a replacement resource. I used it to draft a very snug block and this Patterns of Fashion book helped me to do the rest. I didn't get the fit of the block 100% perfect - the shoulders are just a smidge too wide and I'll have to re-do the block once Laura has got over the trauma of my taking a full set of her measurements.
I think the back came out particularly well. The fit is so snug I was actually quite surprised she could lift up her arms!
