They were surprisingly easy to make, but look pretty professional. My one suggestion for anyone who wants to work with leather/suede: invest in the proper needles for your machine.
The pattern is based off of pair of mittens that I actually own.
Toothless onesie!). Using those as a template I traced my outer suede pieces to be lightly larger. This is so that the lining fits comfortably inside. Because both fabrics are fairly bulky.
Keep in mind when cutting out your pieces that you are supposed to be making 2 mirrored mittens and that the fabrics have good and bad sides. Make sure you don't end up with 2 rights or 2 lefts! When you construct the lining make sure the good side of the fabric is going to be on the inside.
I first sewed my linings together, for the main part of the mitten, assembled the thumb pieces and then sewed the thumb into the thumb hole.
Binder clips can be useful to a certain extent, but don't rely on them too much.
When both the inside and outside are assembled, they are slotted inside one another and a trim is sewn along the unfinished cuff to hold both pieces in place. On the purple ones I just used a strip of my purple suede folded over the edge. On the black pair, I ran out of black suede, so I used a contrasting green suede. This black pair with the green trim was made for my older sister! ;D
