Hello! I made a blazer. As you can see, it's a casual, linen blazer, not a formal, office-appropriate blazer. I used the Heather Blazer pattern from Friday Pattern Company.
The outer fabric is Kaufman Essex Yarn Dyed Classics Woven Linen Check Indigo from Fabric.com. It's a linen-cotton mix, weighing in at 4.45 oz/yard. It feels a little more substantial than my favorite, Kaufman's Brussels Washer Linen, which is a linen-rayon mix. I am happy with my choice, as it's not too drapey. I wanted this to be a little bit structured.
Did I make a toile? No! I just held up the pattern pieces to see how long it would be. I didn't lengthen the pattern at all, and I'm 5'10". I'm happy with the length of the blazer. The sleeves would be a bit too short for me if I didn't roll them up, but I plan to wear them rolled, so this length is fine.
This is a nice, doable way to learn to put in a lining. I have made a couple of lined jackets before, and it is always fun when you finally pull the outer fabric through the gap in the lining and see the almost-finished project! The hardest part was sewing the sleeves to their linings, but I just followed the instructions, worked carefully, and it turned out fine.
