Sew Along, Cosmo Bag! Part 2, the Interior

We are forging on with our Cosmo bag!  If you are just joining us, we started the first part of this bag here.

Let’s get started on preparing the lining pieces.

Grab your lining pocket panels–get one with interfacing and one without interfacing.  Place them right sides together, pin at the top edges and sew with a 1/2″ seam allowance.

Turn your pocket right side out and press along top edge.  Topstitch 1/2″ from the top edge, backstitch at each end.  




Fold the pocket panel in half lengthwise and gently press a crease (you may do the pressing with your hands), this is to mark the center of the pocket.  Grab one of your lining panels.  I’ll wait…

Place the pocket onto the right side of the lining panel, matching the side and bottom edges.  Pin and stitch down the center crease to divide you pocket into 2 sections, be sure to backstitch at each end.  


Now pin and machine baste a 1/4″ seam down both sides and across the bottom.  This will hold your pockets in place.

**I do these steps in a different order from the book, I feel stitching your center first and then smoothing your pocket out onto your panel insures that there will be no bumps or billows.  Or both.


Please repeat above steps to make second pocket and attach to the other lining panel.


To make the lining of the bag, refer to step 6 in the book…I’ll go very fast here…


Get your 4 remaining handle pieces.  With one lining panel and one left handle right sides together, pin and sew a 1/2″ seam, easing the edges around the curve.  Next, do the right handle.  Press and topstitch as you did on the exterior handles.


Complete the steps by sewing handle tops together, stay-stitching, clipping, and folding/pressing in clipped edges.  Repeat for second lining panel/handles.

Now, you need to attach the side and bottom panels to the lining panels as you did with the exterior fabric, refer to steps 8 & 9 in the book to do so.


Let’s make the button loop!

Get your button loop piece, it should be the last man standing…

Fold the button loop piece in half lengthwise, wrong sides together, press a crease along the folded edge. Open the loop, fold each long edge in to meet the center crease, press.

Edge stitch down each long edge, backstitch at each end.


Fold loop in half, matching the short ends.  Then, flip the end lying on top over to the side, placing the finished edges side by side.  Overlap the side edges by 1/8″ and pin together.  Measure and mark 2 3/4″ up from the raw ends along the overlapped edges of the loop.  

Now, edge stitch up the overlapped edges from the raw end to the mark, back stitch at each end.

Fold the top of the loop to form a triangle and press the loop flat.  Edge stitch across the bottom of the triangle, backstitch at each end.


Sew a gathering stitch 1/2″ from the edge, across the raw ends of the loop flat.  Pull the bobbin thread to gather the ends in to measure 1 1/2″.  Knot off each set of bobbin threads to insure that they do not become loose.



Center the gathered end of the loop on the top edge on one of the bands, right sides together.  Pin and machine baste to loop in place.



Now, we will make these pieces look like a bag!  Let’s get to it!

With the exterior right side out and the lining wrong side out, slide the lining over the exterior, matching the side seams.  Pin them together around the outside of the handles and across the top of the side panels.  Stitch a 1/2″ seam completely around the pinned edges.  Backstitch at each end.  Sorry guys, no picture!

Clip into the seam allowance every 3/4″ along the curved edge.  Do not clip into your stitching.

Turn the bag right side out through the opening on the inside of one of the handles, pushing the lining down inside the exterior of the bag.  Press well.

Match the exterior and lining folded edges on the inside of the first handle and pin together.  

Edge stitch along the matched edges.  Backstitch at each end.  Repeat this step to finish the inside edges of the other handle, but first pull out the button loop from your bag sandwich.

**NOTE: This seems to be the most tedious of all of the steps, go slowly, press and pin well.  You may find yourself doing a little bits at a time of pressing, pinning & sewing.  Do it in a manner in which you feel comfortable and doesn’t stress you.**



Attach your button by measuring and marking 2 1/2″ down from the top edge along the center on the front of the bag.  Stitch your button on the mark!



OMG!  Immediately fill up that bag!



Okay, it’s a big bag, sometimes we need big stuff in our life, right??  




Tonight’s the night, guys!  It’s the last day to submit your Cosmo Bag photo to the Flickr group to be eligible to win a gift certificate from this month’s sponsors:  Above All Fabric and Fat Quarter Shop!  

I’ll post tomorrow morning the details of the bag for February, along with the 2 randomly selected winners that completed their bag in January!

There’s snow and ice coming!  If the storm is as bad as predicted, and I do not have power, I will not post.

  1. You make it look so easy! It fealty makes a great bag. I have studied all the contents of your bag and really love the scarf ant that book!
    Congratulations on the great success with this challenge. It motivated me to do something I had never planned on doing, and although I did nit love finishing that bag, I really enjoyed getting my hands back in fabric and on my machine.
    Thanks for that motivation, Bird.

  2. How lovely to find your blog! I am sitting here in London trying to sew a Cosmo bag (I checked the book out from the library.) There aren’t many pictures in the instructions, so I googled looking for help and found you and your sew a long! Thank you so much for going through a mini-sew-a-long and posting pictures. They have been a real help.

  3. Good evening, I see you have managed to make a wonderful bag with ths pattern… I am really struggling with mine, my English is not that great and it s my first bag! So have reached step 9, but am now stuck because of the bottom of the bag… I’m wondering if I understood the step 3 correctly for the bottom pannel, as I have, from bottom to top: the bottom fabric, right side looking down, then interfacing, then the fleece, then interfacing again, then the inside fabric, right side up. All that is “glued” together; the fleece being slightly smaller than all the rest. And how do I attach it to the side and main panels, should I attach both the fabrics to the main and side panels, or only the lower bottom fabric? If somebody could please help me to move forward, I would highly appreciate! šŸ™‚
