I've been intrigued by this Islander Sewing System jacket since I saw Sunni's version.
The pattern comes Janet Prey's Sew Better Sew Faster course on Craftsy.com. This is a great course for mastering new techniques and for understanding factory sewing philosophy (faster, cheaper not necessarily better in my opinion).
I went straight to fabric because I was using a very cheap linen-like cotton from my charity fabric shop. As a result I'm not entirely happy with the fit of garment. I made a medium which based on the measures could have been too small. Sadly its a little too big, even for a relaxed fit. The shoulders are the real problem which sit about 1 inch below my shoulder line. I also think there is too much bulk in the back side panels - a flaw I've noticed in other versions, not just my own. I'll wear it, but don't love it. The big plus is the pattern booklet includes the best instructions for welt pockets and I'll also reuse the pocket and cuff design and methods.
I'll post a picture of it on after it has been washed - astute readers may notice my chalk lines are still visible! Next up I'm finalising my muslin for a basic jacket and trouser block - products of my lessons with my great teacher and pattern making mentor Anita McAdam. I've got some great ideas for jackets and pants which I hope to bring to fruition in the coming months.
