Snowgoose, consider a rag quilt.......accuracy is not a deal breaker and they are super soft and cuddly when finished. The seam allowance is whatever you wpuld like it to be and it doesn't matter if it is a bit wobbly...by the time you get all the fraying happening........fraying hides a multitude of inaccuracy! The squares are quick and easy to put together with just a cross sewn on them to keep the batting in place. And the best thing...like QAYG, the quilt is being made as you make your squares....NO basting, pinning or planning a quilting pattern...just sew the little suckers together and its done!! Yeah, well maybe the snipping of all the seams is a bit of a downer...but, arm yourself with some ragging shears put on a favourite movie and collect several glasses of your preferred adult beverage and just settle in to the task. The quilt pictured took me about 2.5 hours to rag/snip.
Word of warning though...for the first wash you will want to check your washing machine and your dryerfilter frequently as you will get a heap of frayed threads coming off of it. Believe me..its worth it though.
