I'm such an idiot!

So here I go, actually starting on the black partlet for the flemish dress. I zig-zag all the velvet pieces and start attaching the collar. The collar is made the same way as most doublets in PoF, that is; the back of the collar is in one piece with the back piece of the doublet, or in this case partlet and the front pieces are separate. So instead of sewing the partlet together first, the collar then and finally sewing it all together I sew the front collar to the front pieces and then sew the shoulder and side seams. I pin the collar to the partlet and realize that the collar piece is too long. Odd, I think and cut off ca 1,5 cm, zig-zag (both collar pieces of course) and start again. Sew and look at my work. Then I realize that I have attached the collar piece to where the shoulder seam should be, which of course is shorter. So now I have to cut two new collar pieces. I think I will make them a little different than those I destroyed so I will have to make new lining too. But now Maja is asleep in the bed room, which is where I have my sewing machine so no sewing for a while.
