so here are finally the step by step pictures of how I turned my skinny pants into flared pants:
I put the pants on and marked from what point I wanted it to start getting wider
then I cut the side seam off up to that point, inseam and side seam on each leg
then I took that seam as a template
to draw a triangle
and added twice the seam allowance all around (I should have added additional cm additionally at the hem, it was almost to short in the end)
then I took the fabric I wanted to use for this and folded it twice, that way that 4 layers of fabric were on top of each other
then I pinned my pattern to it and cut it
now I pinned it into the pants, wrong side out
at the corner I cut in so all would fit together
and I tried to leave as much fabric open at the later hem as possible, as mentioned it was a little short
then I sewed them in and also used my serger for the open edges
next I pinned the hem at the triangles and sewed
and finished are my new/old pants.
I hope this was helpful for you! Let me know if there are any questions! Suggestions, ideas and wishes are also most welcome.
keep sewing and smiling
