Table Runner and Placemats

 I finally finished my 3rd weaving project, a table runner and 5 placemats.  I was really hoping for at minimum 6 placemats (preferably 8) but when my finished cloth was only 9' long I knew I would be short Oh well, next time I will just make my warp longer.  I do have a bit of yarn left so I may be able to weave three more placemats.  In any case, I had a blast making these and couldn't be happier with the project.

I do have one question for fellow weavers:  If you look at my placemats you can see there is a bit of a "patterned lines" across them.  Does anyone know what causes this, how I can stop it, or possibly make it more uniform?

Thanks for looking.
