Final Week of the Cosmo Bag Sew Along!
We’re rounding the corner on the Cosmo Bag. We hope you’ve enjoyed Rhonda’s expert instruction. Remember you can always come back to the blog any time to go over details or leave a comment on a problem you are having. I will answer them quickly. You can purchase the pattern now if you haven’t done so already and stitch up a fun bag.
Now that we’ve attached the pockets, the hard part is over and the real fun begins as the bag will now begin to really take shape.
There are 3 notches on the Cosmo Bag that are very important and they can be found on the bag front and back pattern pieces. In the picture below, you see the 3 notches marked A, B, and C. The 3 notches will actually help form the bottom of the bag.
I have marked the notches on my bag so that they are a little easier to see.
Begin by folding A up to meet B.
Now bring A and B up to meet C.
Once the 3 notches have been folded together, stitch the notches down by stitching first, 1/4″ from the edge and then stitching again, 1/2″ away from the edge.
As you can see below, the folded notches will form a downward facing pleat.
Place the front and back of the bag together and stitch the side seams and the bottom seam with a 1/4″ seam allowance. Do not stitch the corners closed.
Turn the bag to the right side and push out the open corners. Press seam allowances open.
On either side of the side seam, mark 1 1/4″ away from the side seam. You can see that I placed pins at the 1 1/4″ mark below. The marks are important for zipper placement.
Unzip the zipper and press back the ends to the wrong side of the zipper. Be careful to not completely unzip the zipper since we are using a separating zipper. Once we have pinned the zipper to the top of the bag, we can unzip it, but in the meantime, leave it partially zipped so that you don’t sew the wrong side to the bag.
Pin the right side of the zipper to the right side of the bag, beginning and ending at the 1 1/4″ marks. Sew the zipper to the bag with a 1/4″ seam allowance.
We will now attach the lining to the top of the bag. Be sure to allow the zipper ends to hang into the bag. As you can see below, it is easy to pinch in a pleat into the zipper, so pay close attention to keeping the zipper flat.
Sew the lining to the bag with a scant, so not quite a 3/8″ seam allowance.
Once the lining has been attached to the bag, clip the curved seam allowance.
Pull the lining to the right side. Press the bottom seam allowance in 1/4″.
Edge stitch the bottom of the lining closed.
Push the lining into the bag and press along the top edge of the bag.
To help hold the lining in place, I did a stitch around the top of my bag.
The zipper is installed, and the top of the bag looks wonderful.
Our next step will be to install the tabs for the straps and d-rings. As I was cutting out my pattern, I noticed that an extra set of tabs was included in the pattern, so 2 #10s, and 2 #11s.
You will only need 1 of each of the patterns, so discard the extra set.
Since I am accenting my bag with the leather. I have cut 2 sets of #10s and 2 sets of #11s out of the leather. If you are cutting the tabs out of the fabric, you may cut 1 side in the exterior fabric and the other side in the coordinating fabric. If you are cutting your tabs out of fabric, they will need to be interfaced. Since I am using leather, I will not be interfacing the tabs.
In our final post for the Studio Kat Cosmo Convertible Bag, we will sew up the tabs and attach them to the bag. We will also attach the clips and d-rings and finish up the straps. So we are almost there!!!
If by chance you have not purchased your pattern, but think you might like to give the bag a try, you can find the pattern HERE on the Sew News website.
