We interviewed Anriko about her creation:
Kokka Fabric (KF): What did you think of the fabric you used for this project?
What a fun fabric with unicorns and variety of animals! I personally love animal motifs, so I came up with a large Boston bag so that all animals can be featured.

KF: Can you tell us any special elements or ideas that you incorporated into this creation?
The oxford fabric is soft and it doesn’t normally keep the shape when used for making a large item. At the same time, it can be large yet light and foldable. Taking advantage of these characteristics, I incorporated a design to make it look good even when the bag is not full.

KF: What are some tips for making this bag?
It is large but the process is not that difficult. When sewing the areas with the handles and tab, please make sure to use a larger needle as there will be added thickness.

KF: How should we use this bag in everyday situations?
I intended it to look mature and pop with a black and gold combination. I am sure you will find the bag useful in many ways, as an everyday gym bag and for your summer trips. The handle is long enough to carry over the shoulder, but you could also attach a shoulder belt to a round O ring by not connecting the swivel hook to O ring.

KF: Thank you very much, Anriko! Here are sewing instructions along with step by step photos from her. Enjoy crafting!


While the inside pocket is a patch pocket, the outer pocket is made easier by placing the side ends and bottom in between the layers of fabric. This way it will have a clean look. Please make sure to add stitches along the bottom so that the contents inside the pocket won’t accidentally end up in the bottom gusset

This is a large bag with a long zipper. Here, outer fabric, lining fabric and zipper are all sewn together. To avoid getting the satin lining fabric gets stuck in the zipper, you may add stitches (as shown) if you like.

After sewing the sides and the bias binding tape is applied, sew the gusset by placing a tab with a swivel hook in-between. Slowly operate the sewing machine. Depending on the horsepower of your machine, you may want to move the pulley by hand, paying careful attention so as not to break the needle.

The gusset is also finished with a bias binding tape like the sides. It makes it stronger with tension. It may be an extra step, but it is effective for a large bag.

Use a tab to attach the ring by the zipper. Connect with the swivel hook to finish. You can use either O ring (as shown) or D ring.
