This is one of my favorite fingerless mitts patterns. I like the construction of the mitts; there are so many details and yet it is a very straight forward pattern! I also like it that you can add a second color which gives it such a fun look.

Used long circular needles for the magic loop method (usually not my favorite method, but seems to work well for this project. Instead of binding off and then hemming, I used the sewn bind off while at the same time seaming which I have been using quite a bit and made a video of: binding off and seaming. This is for the picot hem.
On the thumb bind off I used Jenni’s surprisingly stretchy bind off.

11.10. Finished the left mitt, now on to the second one.

Here is an errata which I am surprised nobody else picked up on: I worked the pattern for the right mitt the same as for the left mitt until the thumb gusset (Rnd 25). Then I switched to the instructions for the Right Thumb Gusset until I was back to 48 stitches and continued to work the same as for the Left Mitt. Well, for the Left Mitt the instructions said to change to larger needles before the first decrease rnd (Rnd 27) and it does not say this for the Right Mitt Instructions. So, I just knitted the last 16 rnds on US# 1 instead of US# 2. I will leave it and change to larger needles now, but am kind of unhappy with it :( For the sake of anyone else stumbling over this, this is what it should say in the instructions for the Right Mitt:
Right Thumb Gusset
Rnd 25 as written in pattern
Rnd 26 as written in pattern
ADD: CHANGE TO LARGER DPNS
Then continue as written in pattern.

Of course I just double checked PamPowers page for errata on the Brooklyn Mitts and she did post this errata (click on the link) in 2013, but of course, unless you are looking for it, you don’t know (I must have an old pattern?!).

11.14. Finished the mitts and working now on the short Boot Liners.
