Love the fabric! Definitely gonna give this pattern a try :) Aren't the pattern pieces supposed to be attached with the grey squares touching each other instead of overlapping? This may explain why your size M did turn out fine, while the instructions say it is a rather large and loose fitting style of pants.
Yes and no....while the layout has them touching instead of overlapping every time I have tried assembling the copies that way the sizing lines never lined up...
Yes! Standard patterns have seam allowance built on, so you can just cut around the edge of your size. If your worried about fit I would size up (I made a medium)
It’s 100% cotton and I believe I got two yards, even though you don’t need that much. At the end of the video I linked a video about fabric shopping that’s super helpful. Cotton is usually $4-$8 dollars a yard
