I’m quite excited about this boiled wool top and I’m going to make several more. It’s the sleeveless version of the LB Pullover from Paper Theory.

There are no alterations to the pattern except for length, though I have changed the construction to suit the boiled wool.

Lapped shoulder seams

I lapped the shoulder seams as shown in the really clear video from @LeilaSews from @MunaAndBroad at https://www.munaandbroad.com/blogs/news/overlapping-seams-for-your-mallee

I drafted a 2-inch Liberty Tana lawn facing for the neck even though boiled wool doesn’t fray. That’s because this is a heavyweight boiled wool and slightly prickly. I sewed the facing on right sides together, understitched it, edge stitched it from the right side and then at the outer edge of the facing. I’ve started hand basting facings now before sewing instead of using pins. I find it much more accurate and less stressful, because generally it then works first time.
It’s hard to tell the difference between the back and the front of these tops when they’re finished, so I sewed a tag in under the back neck facing. Otherwise this can be quite annoying in the morning when getting dressed!

The cotton protects my neck area. I will always be wearing this over something else so the itch factor doesn’t affect me elsewhere.
I self-faced the arm openings with 2” strips of the boiled wool. I sewed these on after closing the shoulder seams and before sewing the side seams.

I sewed the side seams as normal. I didn’t do anything to the hem except top stitch around the edge to avoid any stretching out that might happen later.

I got the fabric from http://www.quiltyarnstitch.com
I sewed this grey one last week and it didn’t need neck facing because it’s a softer boiled wool.

The dress underneath is a Cashmerette Pembroke that I made last year.
