I am on my second Blackwood cardigan and already planning my third, this is such a versatile garment. The two I have made are both the longline version, and the next one will be the short version. It is a really simple make, and the instructions are very clear. I made both of mine on my sewing machine using a walking foot, then overlocked the seam allowances, as the fabrics I used were quite thick. It could be made entirely on the overlocker in which case it would be a super quick make.
I shortened it by two inches as I am only 5’4″.
Take a look on my blog for more details on my make: https://sewminigems.wordpress.com/2020/01/19/blackwood-cardigan-essential-basic-for-your-me-made-wardrobe/
