What You’ll Need:
● Main fabric
○ 17”x28” piece
○ Consider a medium-heavy weight fabric to maintain some structure when bag is open
○ E.g., canvas, denim, twill
● Lining fabric
○ 16”x28” piece, cut into 2 pieces
○ Consider a waterproof fabric if you anticipate any leakage
● Pellon 975 Insul-Fleece
○ 16”x28” piece, cut into 2 pieces
○ Specialized batting (80% Polyester/20% Metalized Polypropylene), designed to insulate i.e., keep hot things hot and cold things cold
● 1” webbing (ready-made or make your own)
○ 4” length, cut into 2 pieces
● 1 G-hook or Side release buckle that accommodates your webbing width
Note: In this tutorial, I am using a 1” metal G-hook, 1” cotton webbing, 100% cotton twill as my main fabric, and a repurposed 100% polyester blackout curtain as my lining fabric. My final bag sample in the pictures for this tutorial was 3.5” more narrow than intended, as my math was not cooperating when I cut out my pieces, so yours will be the appropriate size, I promise!
