Progress, But I Need a Plan...

You can't get a suit of armour and a rubber chicken just like that.  
You have to plan ahead.

Thanks to my husband's anchor and my weaving friend's warp, I am making good progress on my current project:  

It is about 5.5 inches wide, and I'd like to make it into a small purse.  My thought is to fold it twice - one fold to create the front and back of the body, with the back being a bit taller - and then to fold over the excess of the back in order to form a flap.  

That is as far as I've gotten in my "plan" - there are several open questions that need to be addressed:  

Holding the flap down - the metal snaps that I've used in previous bags seem a bit too heavy, I don't really want to add a button hole...  

Also, how should I stitch it up?  The fabric is kind of thick, and I'm afraid that turning it inside out and stitching up the sides might not work well.  

Finally, my weaving friend recommends lining it, and I agree - but I'm not sure exactly how I would go about doing that.  

I definitely need a plan.  

Any suggestions where I might find a suit of armour or a rubber chicken?  ;)

Or maybe just some thoughts on how I might turn this piece of hand woven fabric into a little purse...  ;)
