Quilting

I think everyone who reads this blog knows I like to sew.  I like making clothes for my kids and occasionally for myself.  I like making toys, especially dolls.  I like making bags, things for babies and even simple tied blankets.  While I don't really enjoy it, I appreciate the ability to make home decore items like curtains and throw pillows.  I find making beautiful, useful items very satisfying.  So, I should like quilting, right?  Quilting is a beautiful, useful craft.  Many quilts are truely works of art. 

I've finished three pieced quilts my whole life.  One was done with my mother's help, one taught me that knit fabrics and quilting don't mix well and one turned out ok, but is nothing special.  Right now I have two pieced quilt tops lying in my sewing room waiting for me to layer them and machine quilt them.  I'll get to it...someday.  These last two quilt tops have taught me why I am not a big fan of quilting.  I work hard at being as exact as possible with my cutting and sewing.  When I make clothes you are never going to notice if the seam is 1/16th of an inch off.  But when you piece a quilt and are even a tiniest bit off in cutting or sewing and you continue adding pieces that are a tiny bit off the whole quilt top goes from being the apropriate rectangle with 90 degree angles to something that will not fold staight no matter how much you trim it.  I find the whole thing SO frustrating.  Are other people really able to cut and sew perfectly straight seems?  Is this something that would get better with more quilting practice?  Am I being too hard on myself?
