It’s kind of improvisation, I don’t know, what it should look like at the end…:)
I washed it when I finished the back part, to see if I’m right with size, and it is exactly as pattern says (just the armhole was too long, but it was not such a problem to repair it)…see photo.

I made two small holes in waist area for belt… So the belt is not visible on your back, only in the front…

The front pieces I’ll made in stockinette, acording to another Ravelrie’s projects it looks nicer to me.

Edit 1.6.2015: I had to redo the upper rim. I did not have enough yarn before, but I have now (thanks you, Drops sale:). The rim was too short and too loose, so it fall of the shoulders all the time, pretty annoying! So I added about 4 new garters and dec about 3x 10st evenly in part between shoulders… Now it fits better. (Photos are taken before the editing)
I also made a new I-cord string, with little wooden beads in the ends… Lovely!

Note to myself - yarn remains:
after back piece: 62g of Zauberball, 22g of Alpaca
after one front piece: 52g of Z., 21g of second ball of Alpaca

I love this project so much, that after it was sold, I made another one in different colour… :)
