I used the Samu Sweat Jacket pattern from Ottobre 6/2007 in size 140, which is a size up from his current size. I usually buy or make the kids' outerwear in a size too big, especially for spring and fall items. Otherwise it seems like they outgrow things before they've even worn them much.
The primary design feature is that the pockets and top of collar have raw edges. I'm pretty indifferent to it with fleece, although it sure was simple! I think it is a more effective look with the recommended sweater/sweatshirt knit.
The inside collar seam is finished with bias tape. I love that, and I'm sure O will appreciate it too, since he tends to be sensitive about seams and tags near his neck.
Overall it went together well. Some of my topstitching is a bit wonky, but it doesn't show much on fleece. I also could have done a better job with lining things up across the zipper (the hem band, pockets, collar, topstitching). Everything is just a little bit off, but no one else is likely to notice that when he's wearing it. But now you all know because I mentioned it.
He tried it on last night before I had the zipper in and declared it a success. Now it just needs to warm up again so he can actually wear it! It was pretty springy last week, but got cold again and snowed yesterday. I'm so over it.
