Hi, I finally manage to sew something for myself!
Here is the hoodie:
here is the how to :
First you have to cut the skirt's panels.
Then cut out two bands out of one of the sleeves, you need them to be a half of your waist size and add about 5 mm to the length for both bands, for ease. If your waist is 66 cm, then you need two bands of 33,5 cm. The height of the waist band for me was 4,5 cm, do not forget to leave 1 cm seam allowance all around.
Now you have all two pieces for the skirt.
Now, back to the skirt's panel, first you need to unsew a small part on one seam to insert the zip, secure the seam with your sewing machine.
Serge the top edge.
To make the gathering you need to sew a straight line on the panels at 1 cm from the top edge, secure that straight line with a back point but do not do it at the end, leave a good amount of thread a the end.
Now just pull the under thread (the one that cam out of the can on your sewing machine).
See it's starts to gather, do it till it matches the length of the waistband
Now the waistband; sew the two bands together and iron the seam flat, then apply some fusible to the wrong side of the waistband, to give it some strength and serge the band.
Fold it in the length and iron it.
Sew waistband and skirt together following the gathering line on the skirt.
Pull out the gathering threads.
Iron the whole thing, and you are done!
the final result as a skirt:
