2nd time's a charm

This is my 2nd jacket. The first one had some sizing and user errors. (orange fine wale cord, was epic fabric!) I used a too-stiff interfacing on the first one, so this one i softened it up. The orange one i made the C cup and it was too big, even though i did create a muslin for sizing. I did find the C-cup dart too sharp, it needed some modification to not be so 'pointy'; the teal one i used the standard front and not the C cup. The pattern was well designed and well instructed. I wore this to a Chamber of Commerce event last night and received many compliments!

The blazer

The pattern and tutorial were great. I am 74 years old and took tailoring classes in 1967. It had been a long time since I made a tailored blazer. I am fairly pleased with my completed blazer and am staring on a new one. I found the step by step videos to be helpful and inspiring. When my blazer was completed I ordered the pattern from the copy shop which will make the next one much simpler. I ordered the packet with to complete the inside and found it to be very helpful.
I completed the blazer during a time while healing from an injury which prevented playing pickleball 😩. What a great distraction.
I recommend the pattern and tutorial.

I have not made this yet and after looking at the pattern I feel its too much work. I guess I thought it would be simpler. I also dont know where I can locally buy some of the interfacing that is required. I really dont want to order on line.

Very thorough, great sizing

I have not had the time to finish my blazer, but I'm very happy with the detailed instructions and especially with the alternate pieces for larger bust sizes! It makes a complicated project one step easier and I wish all patterns had these options. A lot of the hardest work has been done for you. I have made my muslin (most important alteration was taking off 3 inches of length overall, as I'm very short) and I'm confident I can turn it into a proper blazer with these great instructions.
Would definitely recommend!

Oh, Jasika Blazer. You Complete Me.

Shall I compare the Jasika Blazer to a summer's day? Thou art more stylish and more inspiring than the darling buds of May. Okay whatever, just get yourself this pattern, Sewists of the World. Thank you Closet Core for not dumbing down this blazer, but also giving sewists ample support and encouragement via your course (upgraded my sewing game forever), tailoring kit and general online rah-rah presence. I thought after I made it, I wouldn't want to sew another blazer for a very long time. Not so! I made one in Harris tweed and immediately made another in linen for summer while I still had the pattern pieces strewn about my space and Heather Lou's double clapper song in my heart. The FBA on a platter was like a shiny, golden gift from the boob god(desses). Every time I see my blazers hanging in the closet I have a little moment of "I can't believe I made that" and every time I've sewn a garment since then (I'm looking at you, Blanca Flight Suit and Ginger jeans) I feel like I'm sewing with more love, integrity and skill because of all the nuggets of wisdom the Jasika course bestowed upon me. One million freakin' stars!
