I am currently working on the Butterick 5251 knit cardigan. I have to mention, it's coming along nicely. It is turning out to be a wonderful looking knit garment. This will be a long post with lots of pictures for your viewing pleasure.

This is a
close up of the bulky sweater knit I am using for this knit cardigan. It's a pretty blue and dark brown diamond patterned knit that I found at G-Streets. I had about 2 yards and 2 inches of this fabric. Turns out it wasn't enough to fit the belt pattern piece. Since this fabric had a 4-way stretch, I was able to reposition the belt pattern piece along the selvage.

Here's the
fusible knit interface applied to the collar. I used Pellon's Easy Knit (that's what it said on the paper that came with it). I applied and fused it with a damp press cloth and medium/high heat setting.

Here, I am
pinning the front pieces to the back piece. I match my notches first and then match the ends. Then I gently pin along the seam line and careful not to stretch the knit fabric.

I'm sewing a
5/8 inch seam using a narrow zigzag stitch. Once I'm done with the seams on my SM, I go to my serger and finish the seam edges. I stitch about 1/8 inch away from my SM seam (main seam). This gives the seams a nice finish as well as reinforces them. Sorry, I forgot to take a picture of the finished seams. I will include a picture in my next post.

To give you an idea of the
narrow zigzag stitch I used, here's the display on my SM. This shows what the actual stitch would look like. Your SM stitch settings will be different than mine. This gives you an idea of what you should try to get your machine to stitch out.

Here's a picture of the narrow zigzag stitch I used. As you can see, it's not quite a deep zigzag and not quite a straight stitch. The narrow zigzag gives the seam some stretch and prevents the stitch from popping or breaking.

Here's the collar after it is sewn together (interfaced with non-interfaced). I pinned the back collar area away from the seam line.

This is the first time I am sewing a knit on my Sapphire SM. I tried sewing a knit over a year ago and had some issues. I guess with experience and getting to know my SM, I didn't encounter any problems with sewing this sweater knit fabric. You'll notice the thickness in the picture. That is about 5 layers of bulky knit fabric. I set my SM speed to the slowest setting and it did not hesitate one bit.

Save the best picture for last. Here's the collar and front facings installed. The collar is actually a bit wider than what's presented on the pattern envelope picture. The line drawings appear to be exact. I think I have to get used to the collar. It just seems a bit wide towards the bottom when I tried on the cardigan. I do like the style...very contemporary looking.
This cardigan is about 80% completed. I still have to finish (hand sew) the collar back, hem the cardigan, topstitch the hem and front facing areas, and create the self fabric belt. I will be back with more pictures and another post later.
Happy Sewing!
