A weaving project redeemed

So I have been working here and there on a couple of weaving projects.  Most recently on my rigid heddle I decided to try the Log Cabin pattern described in Jane Patrick's The Weaver's Idea Book: Creative Cloth on a Rigid Heddle Loom.  The pattern is derived using two contrasting colors from the warp and weft crosses.  I thought it would be simple.  It was not.

My first mistake was the way I threaded it.  I miscounted the number of threads in each color block, and then I sleyed the reed entirely wrong - instead of alternating light-dark (or vice-versa) in the slot and holes, I grouped the colors together by two (one slot and one hole both the same color) which gave me a lovely houndstooth-style cloth.  So, lovely, but not the original aim.  I decided to completely re-sley the reed to try and get the pattern I had hoped.  Success!  Except that the back of the reed looked like this:
 

 Messier than I would have liked, for sure, but it all straightened out in the weaving:
 

Because I had to rearrange the threads at the back, pulling some out of the warp and tying them together, a few of the remaining warp threads did not get caught around the back beam.  Which was fine until I got near the end, and they grew so loose I could not get the yarn to lay smooth when I beat it down.  In the end, I opted to cut it off and tag it as a learning experience.

Here's the finished piece, which is less of a table runner and more of an oversized placemat:

My selveges are a little messy but I will stitch them under before displaying it on a table.  Given that I thought this was going to be a total loss when I first started it and it was not, and that I got this yarn on sale and will be able to do another similar project with it, I am not at all unhappy with how this turned out.  True, it would be great if these things turned out right the first time, but Rome wasn't built in a day.  Hell, sometimes I can't even get the loom threaded in a day.
