this is most excellent DIY project. How much work was it? post your design process?
I should have kept better notes, but here's what I got. I'm going to go in the order that I made it, which was split in to 3 sections after I list the materials below. Total time was about 5 hours. That included screwing around with the sewing machine which I hadn't touched since high school, and sewing slow because of inexperience.
Materials:
- 1 1/3 yd. Polyester fabric for Inner lining (They sold me the extra for a discount.)
- 1 yd. Cotton Fabric for Outer lining
- 2 yds. Insulbright For Insulative Layer
- 48" Zipper
Note: I had left overs of all fabrics but not a ton.
Design:
1. Lid
I measured out the lid portion by measuring from the center of my lid, to the other rim. I then added an additional 2 1/4 inches to the total.
From here, I took my measurement from step 1, and "compass style" with string and a colored pencil, I drew a circle on the cotton fabric, polyester fabric, and the insulating fabric.
Cutout these circles.
I then joined all 3 fabrics, Cotton > Insulbright > Polyester, and sewed with a sewing machine.
After the top is complete, sew the top edge of the zipper along the edge of the lid. Afterwards, set aside.
2. Bottom
Repeat the steps above to create the bottom lid, of course without adding a zipper.
3. Middle Piece (24H" x 48"W)
I then moved on to the biggest piece of the fermenting jacket. I measured out a piece of cotton fabric 24 inches high by 48 inches wide and repeated this for the polyester, and Insulbright fabric. You should have 1 cotton layer, 2 Insulbright layers, and 1 polyester layer.
I joined these pieces together by sewing both layers of Insulbright between the cotton and polyester layer, along the top edge. I then repeated this along the bottom as well.
Once complete, join the two un-sewn edges and sew together. (I slightly overlapped each end.)
4. Joining the Lid and Bottom
Once all 3 pieces are complete we need to join them to the Middle Piece in Step 3. To join the lid, take the un-sewn edge of the zipper, and sew it to the top edge of the middle piece.
Sew on the bottom portion to the bottom portion, be careful to have the cotton piece facing outboard.
Voila! You should now have a complete fermenting jacket.
P.S. I apologize in advance, I kind of played it by ear and adjusted as I went so I don't have super exact numbers/processes.
