What Are Some Expert Bag-Making Tips from Minki Kim?
Minki Kim, a fabric and pattern designer known for her whimsical "Sewing Illustration" style, shared several practical bag-construction tricks on 3 Things Live, including attaching binding before assembling a bag rather than after, using a topstitching needle for a noticeably cleaner finish, and cutting panel pieces slightly oversized to account for shrinkage during quilting. These are small adjustments, friend, but they're the kind that separate a bag that looks handmade from one that looks like it came off a shelf.
Some of the best sewing advice doesn't come from a pattern's instructions. It comes from watching someone who's made the same project a hundred times and picked up a handful of shortcuts along the way. Designer Minki Kim shared exactly that kind of advice while walking through one of her bag patterns, and a few of her tricks are worth stealing for your own projects.
1. Attach the binding before you assemble the bag
Most patterns have you assemble a bag into its full three-dimensional shape first, then attach binding around the edges. Minki does the opposite. She attaches binding to each flat panel piece before anything gets sewn together into its final shape. Her reasoning is simple: it's a lot easier to sew binding onto something flat than to fight with it once the bag already has depth and structure.
2. Skip hand-stitching binding down, use fabric glue instead
For binding that won't be visible from the outside, Minki stitches it down on the right side of the fabric, then flips it over and secures the back with small dots of fabric glue rather than hand-stitching it. Her rule of thumb is that hand-stitching is worth the extra time only when the stitching will actually show. If it's tucked inside a lining, glue does the job just as well, faster.
3. Try a magnetic snap instead of a zipper
If zippers feel intimidating, Minki's workaround is worth knowing. Instead of installing a zipper, she sews a small pocket into the lining and tucks a magnetic snap inside it, giving the bag a secure closure without ever touching a zipper foot. It's a genuinely beginner-friendly substitution that still looks intentional rather than like a shortcut.
4. Cut panel pieces a little longer than the pattern shows
Quilting shrinks fabric slightly, and how much depends on your specific quilting density and pattern. Minki's fix is to cut her panel pieces roughly half an inch longer than the pattern indicates, quilt as usual, and then trim down to the correct size afterward. It's a small buffer that saves you from ending up with a piece that's suddenly too small after quilting pulls it in.
5. Switch to a topstitching needle for quilted panels
This one's a simple supply swap with a real payoff. Minki mentioned only recently discovering topstitching needles for this kind of work, and noticed an immediate difference in how much smoother her stitching moved through quilted layers. If you've been using a standard needle for topstitching heavily quilted panels, it's worth having one of these on hand to compare.

Frequently Asked Questions
Should I attach binding before or after assembling a bag?
Attaching binding to flat panel pieces before assembly, rather than after the bag is sewn into its final shape, tends to be easier to work with since you're sewing on a flat surface instead of a dimensional one.
Can I use fabric glue instead of hand-stitching binding?
Yes, for binding that won't be visible from the outside of the finished project, fabric glue is a faster alternative to hand-stitching and holds the binding securely in place.
Why would I use a magnetic snap instead of a zipper?
A magnetic snap tucked into a small interior pocket gives a bag a secure closure without requiring zipper installation, making it a good option for beginners who find zippers intimidating.
Why should I cut fabric pieces larger before quilting?
Quilting can shrink fabric slightly as the stitching pulls the layers together, so cutting pieces a bit larger than the pattern calls for and trimming down afterward helps ensure your final piece is the correct size.
