There are 3 more t-shirts 2 from the b-positive pattern with the split sleeve - Ottobre 03-2015-17:
And one regular raglan tee - Ottobre 01/2016#11 - Bla Bla Raglan T-Shirt:
The black fabric was far from stiff so I interfaced the hell out of it both the exterior and the interior. For the black one I used the same fabric on both inside and out and with all the interfacing and more layer of thicker fabric it turned out a bit to tight on my son so there it is a good chance it will be Eva's. Even if it is a boy hat I think it looks cute on her as well.
One the gray one I use a thinner cotton for lining and O only double interfaced the brim. It looks better and I got the fitting better as well.
For construction I didn't use Ottobre instructions. They talked so much about allowances and interfaced that I got bored really fast . I just constructed the interior and exterior separately leaving and opening on the interior one and then joined them at the outer brim. Clipped and clipped and then clip some more. Ironing also helps a lot. Turn and top stitch the brim to stabilize it in place.
One very important note is to mark each piece and marking quite carefully. It's very easy to confuse them and lose shape because of it. I think the black one it just a little bit off but the for the gray one everything clicked perfectly since I was paying more attention to marks and ofc ... practice always helps.
