I found an adorable duffle bag pattern! It's a free tutorial from Bernina. Click the link to go to the tutorial:
The finished size of this duffle is 14.5" by 8" by 8" tall. I have kitted this project in case you want to make one too. The kit includes the laminate, the cotton webbing and a black zipper.
You can click the link above to go directly to the item in my online shop. Or you can go to AlamosaQuiltCompany.com and click Shop>Kits and this one is probably the first one that will show up since I just added it to my online shop.
