sounds like you are talking about making the blocks into a raggy quilt- simply put the back sides together- stitch with a 1/2" seam to join the blocks- when all is together- clip the exposed seams about every 1/8"-1/4"- to the stitching line, being careful not to clip your seams...
take it outside and give it a good shake then toss into washer/dryer-
empty the lint trap about every 20 minutes on the dryer- all those little threads will really build up quick.
i usually take the quilt out of the dryer 2 or 3 times during the drying time and take it outside to shake it again...just to keep the loose threads to a minimum in the dryer.
you will have a quilt with (chenelled) frames around your blocks---very cool!
