Darcy’s Law tells us that the flow rate of water through the coffee bed depends on the permeability of the bed and the pressure difference. This explains why grind size is critical. If you grind too fine, you reduce permeability, increasing the resistance to flow. This leads to a stalled brew (often called "channeling" or "stalling" in espresso and filter respectively), where water finds paths of least resistance, leaving large sections of coffee unextracted while over-extracting others. The equation is: by Jonathan Gagné
Did you by chance buy your waxed canvas online? I’m looking for something just like that to make a new bag and it is hard to find!
Hi Mariah! I am also using waxed canvas for my next bag. I bought this piece on Etsy (https://www.etsy.com/shop/bagsupplycompany), which is okay for a yard or two. If you need a lot, you might want to contact Fairfield Textile who can sell larger quantities. Look for Martexin Original Wax. They have a cutting fee for small orders, and shipping is usually pretty expensive because it ships on a long roll. Hope that helps!
Bag making is very interesting. I saw your other bags. That’s what I do the most of, though I make clothes like a recycled denim vest recently. Have you worked with stretch fabrics yet? Pullover shirts are a breeze with a nice cotton stretch; slap on a patch pocket and I like to put an Mp3 pocket just above the waist ad off to the side where comfortable.
So I got something recently I want you to see, knowing you have your industrial machine. I got a post machine that makes chain stitches. Check it out at

This is a fabulous pattern. I found you on the Sew Mama Sew site. I ordered my waxed canvas at Red Rabbit Mercantile .https://www.redrabbitmercantile.com. I used leather handles – Red Rabbit was happy to put a hardware kit together for me and it arrived quickly. I love the results!
Thank you! Glad you like the pattern.
Hi Taylor,
Found you on www.madalynne.com. This is a fantastic bag. I’ve just recently started working with thicker fabrics like these. Going to need to research this. I love the weathered look it has. So beautiful.
Cheers,
Natalie
