I finally got to work on my blouse again today and did the slit you wanted a tutorial for.😉
measure how long your slit is, including the seam allowance
start with 2.5 cm or the width you want that additional part to be, when translated the german word for this slit is rooftop-slit, I guess for the triangle at the top
then make a box with the slit length out of it
add another one to the side in the same size
on one side go 2 cm up
then do the triangle part in a 45° angle
looks like this
add seam allowance all around, but not to down end, because the seam allowance is already in the slit length included
cut it 2 times, mirror images of each other
then copy the main slit form from the pattern
and cut it in thick paper
and use that to iron around it, first the 3 sides of the main part, then fold the other over, the corner on the end, and the seam allowance inside pretty much finished
first you need to roll the side of the slit closer to the sleeve seam over twice and sew it in place
then pin the slit to the other side
and sew close to the fold around the top triangle until 2 cm more down and then in a straight line back to the other seam
when pinning the cuff to the sleeve remember the cuff ends with the slit part and has additional cm at the end where your rolled in twice looks like thismy blouse looks like this by now, I need to do hand-stitching at the inside of collar and cuffs and do the buttons I’ll show you how it looks when its finished.
For all the blouse steps please look here. If there are any questions left about the slit, do not hesitate to ask.
By the way: The drawing voting is at a tie in the moment, so if you havent voted yet, please do so here.
