David said: Most seams are overbuilt on commercial packs. They can be a bear to patch if damaged (by say a bear) and you need to take out a seam in the process of repair.

You can say that again!

Wwwweeeeelllll ... if the "BPL Community" had put enough effort into the WIKI to keep it alive then we'd have such a place. But we didn't.

"It's too bad we don't have accepted seam definitions with diagrams to work with on this site"

I agree. I don't think there's 100% consistent definitions anywhere

thru-hiker.com has some good description under "projects"

French Seam

Under basic seams it describes simple seam and what he calls "felled seam" but is more commonly called "flat felled seam"

Those are about the only seams you need

You can do a flat felled seam with just one fold, leaving raw edges exposed, if you want it not so thick in case several seams overlap and it's difficult to sew through all of them. I forget what that's called.

I've posted this before:

But there's a problem: getting people to agree to use the same language. No one says 'an LSc seam', they'll call it a felled seam or a lapped seam.

Samuel: "Don't know what a 'basic flat seam' is"

Yeah I don't really know what to call it either I guess. I just mean the easiest type of seam where you put the two pieces of fabric wrong side out and sew with a seam allowance, and then invert the seam to finish. My whole pack is sewn this way with Rasant 75 thread. I don't really mind about more or less needle holes since the seam grip should take care of those.

Edit: on Thru-hiker they just call it a "simple seam" http://thru-hiker.com/projects/basic_seams.php

What sort of seams does your current project have?

A bit of blaming the victims, perhaps?

BTW, when the WIKI started, I couldn't get into it, put time into making inquiries (have you ever tried to contact BPL on this site?-reminds me of the IT people at work), and got no comprehensible or workable answer.

Jeremy, now I think I know what you meant by 'basic flat seam,' but still not sure, because what you describe would be anything but flat, unless you rolled it over at stitched it down. But that probably makes no sense to most readers, either; which is why we need a simple standard reference.

I've put diagrams up before, but a few months later have seen the same confusion repeated on new threads. When I get time, I'll do up a set of diagrams with their common names, put it in a small jpeg form, and just keep posting it until rockets start coming into the back yard. In the meantime, it's hiking season, and getting out there is priority one. The bugs are just starting up and should peak in a few weeks, but I'd rather spend indoor time during bug peak modding a tent down to lighter weight to use this summer.
