MYOG pack advice/help please on 11/16/2012 17:20:29 MST Print View

Hi all,

I'm currently working on a small 20-30 liter pack for myself. I intend to use it mostly as a daypack, or an overnight pack if it turns out bigger than expected. Everything is coming along fairly well so far. I'm not using any patterns, but I'm loosely basing the design from some of Zimmer's packs.

What I need is some guidance on forming the bottom of the pack. I've got the back, sides, and front panel all finished. However, I'm not exactly sure how to form the box like shape for the bottom.

Here is what I'd like to end up with for the bottom.

it ought to be constructed much like a bathtub floor.

take a rectangle of fabric that is the size of your base, plus the size of those side walls (4"?) plus seam allowance.

draw a 4" (or whatever side height you chose, plus seam allowance) square in each corner. fold each corner right side to right side, bisecting the 90deg angle of the corner, and sew along the two sides of the square which will now be lined up.

trim off the triangle of extra fabric, leaving seam allowance. fold over twice, sew through.

repeat for all four corners.

then sew this onto the already assembled tube that forms the upper portion of the pack. use the seam of your choice, i would choose flat-felled. make sure the seams on the bathtub bottom end up on the inside of your pack

think carefully about lower shoulder strap webbing attachment. ditto with hipbelt. both could be sewn into vertical seams of bathtub, if dimensions work.

Shoot me an email with your pack dimensions and I can draw you something up.

Thanks Adie,

I've done a bathtub floor before, so that makes perfect sense. I'm a little leary on attaching the completed bottom to the rest of the pack. I assume this would be done easiest with everything turned inside out.


I appreciate your offering to put something together for me. I will get those dimensions over to you here in a few.

Thanks again for the help everyone.

Is the rest of the pack sewn together already? If it is not, then you can sew the main panels to their corresponding bottom panels, then make the vertical seam continuous.

No I havent sewn any of the pieces together yet. When I started to look at piecing it all together I hit a mental block. I just couldn't see how it all came together. I've got a little more understanding of it all now. Hopefully I can get it together without ripping too many seams.

The bottom will be shaped like the top of a cross. The top will be for the center panel. The sides for the sides. Just attach the sides to the side panels of the cross (I'd use a flat felled seam). Connect the front to the top of the cross. Then sew it together like you would without the bottom.

Thanks everyone,

I'm back on track now. Just waiting for my spacer mesh to come in to finish the shoulder straps.
