Skill level: Intermediate (Must have basic sewing skills to make a zipper pouch.)

I will teach you how to properly make boxed corners on your pouch and how to get the bottom width size you’d like!

Tools Needed:

OLFA RM-SG 18" x 24" Green Double-Sided, Self-Healing Rotary Mat

OLFA QR-4S 4 1/2" Square Frosted Acrylic Ruler

OLFA 5-Inch SCS-4 Straight-Edge Stainless Steel Precision Scissors

Frixion erasable pen or similar marking tools - chalk, pencil, etc…

Fabric Requirements:

You will need an “almost” completed basic zipper pouch shown to the point below. Zipper has been installed and seam has been top stitched.

Cutting Instructions:

1. Take your 4.5” OLFA Square Frosted Ruler & mark each corner with your pen at 1” width & height.

2. With your 5 nice Straight Edge Precision Scissors cut each corner out of both your exterior & interior fabrics. If you’re afraid the fabrics will slip, pin together.

Assembly:

1. Make sure your zipper is open.

2. Now pin your exterior pieces together and your interior pieces together as you normally would when making a zipper pouch.

3/ Sew around your pouch leaving a gap to flip as per usual.

4. Now take each corner, open the seams and pinch as shown. Pin to hold in place.

5. Sew each corner flat with a ¼” seam allowance.

Your pouch will now look “pillow like” as shown. Flip your pouch & close opening. Your pouch should now have lovely boxed corners giving your pouch a 2” base!

PRO tip! For whichever size you choose to cut your squares, it will give you double the width. So for my tutorial we cut 1” squares and ended up with a 2” base using a ¼” seam allowance. Here’s how other sized squares would measure up!

The bigger the square is cut, the taller/wider the pouch should be or you’ll end up with an awkward shape, or just simply a triangular pouch! Which is also fun!!

Playing and experimenting is the best way to achieve the look you like!
