0:05 Overview
STEPS:
6:50 1. Decide on design and shape, total weight of down fill and weight to go in each section, width of sections and buffles size. Also, think if you like to make zipper flap to prevent heat loss, like in this video
13:06 2. Cut fabric into shape (both outer and inner parts). Use masking tape to hold fabric in place
13:20 3. Mark buffle sections locations with fabric pencil or chalk
13:49 4. Synge fabric to prevent fraying
14:55 5. Mark and cut buffles strips (unless you have mesh in a roll - highly recommended).
18:45 6. Hem outer and inner fabrics on ALL sides. Use 1/2 inch or 1.25cm seam allowance. 1 stitch line is enough
19:50 7. Add vertical buffle if you plan on adding zipper flap. 1/4" allowance
20:48 8. Sew in horizontal buffles
22:09 9. Sew in buffles to outer/inner fabric connecting them both
23:15 10. Use fabric glue to catch vertical buffle on one side of the outer. Using glue is very helpful in holding all fabrics together and really helps during stitching together later on.
24:45 11. Make reinforcing triangle to go between end of zipper and foot box. It should be of same fabric as upper but folded twice to make it stronger.
24:50 12. Add this triangle to a place where end of zipper going to be and attach to outer fabric. You may also add a strip of reinforcing material to go between fabrics to make it stronger. Use fabric glue or pins. Once in place stitch it in
25:20 13. Measure out zipper you like to use. Attach one side of zipper to upper fabric in step 10. Again, use glue to catch parts together. Also, using pliers to press fabric together helps create stronger bond
25:22 14. Attach inner fabric, to outer fabric in step 10 (if using flap , than to flap). Again use glue or pins
25:25 15. Stitch inner and outer and zipper fabrics together. Go slow and take your time. Do at least two lines of stitching. Keep zipper closed not opened, otherwise one side might be longer and it would be hard to match lengths of each side when doing the opposite side.
25:49 16. Reinforce the ends well, both at the end of bag and the top
26:17 17. Close the bottom of the bag by stitching the lowest section shut. Do at least two lines
26:40 18. Make a shock cord sleeve for the hood. It should be 2-2.5 inches (6-7cm) in width. Just fold once and stitch along one side. Once done sew it in at the top of bag and close top section
27:10 19. Cut fabric for foot box. Easiest is round or oval foot box. In this case 35cm x 25cm or 15 x 10". Cut buffle mesh for mid section
28:10 20. Connect both outer and inner together using buffle.
28:35 21. Use pins or glue to catch most of foot box material shut and then stitch closed everywhere except very top. Leave few 2-3 inches open at one end where you will add down.
28:50 22. Weigh desired amount of down and fill foot box sections. Close with clips or pins
31:50 23. Fill zipper flap with appropriate amount of down. Using paper towel or other tube works well. Close with pins.
24. Before filling the main sections I recommend to first stitch zipper flap
32:47 25. Fill in main bag sections. Folded cardboard paper in a form of a cone works well. Use tape to keep paper in shape. Fill by handfuls and use something like hiking stick to push into section. Once filled with desired amount, close off sections with pins.
35:00 26. Stitch foot sections close
35:09 27. Turn bag inside out and attach foot box to main body of the bag. Use pins to hold in place while stitching. Do at least 2 lines here, preferably more
28. Move back to side with pin closed sections. Open one by one and add other side of zipper. Use glue to catch it in place and hold with pins.
29. Stitch the other side together. Make sure to do at least two lines and reinforce the ends like in step #16
36:18 30. Open zipper and add sliders. Make sure you use thinner end of slider on the bottom. Add 2nd slider if desired, but using opposite side of it to get on zipper
37:48 31. Feed shock cord through hood sleeve. Using old pen or wire helps here.
32. Add cord locks at the ends and tie knots at the ends to prevent sliding off
DONE!

As DIYers, we were tired of settling for generic fabrics while big companies had access to all the good stuff. So we launched Ripstop by the Roll - an online community for makers to find the world's best materials - plus the knowledge on how to use them - to successfully make their own gear or grow....
