I had a very lucky find in my charity shop today which has alot of squares already hand quilted with the top, batting and backing all the same size - remember seeing a method of joining blocks together so that the seam is on the right side, then you pull some threads to create a fluffy effect!!! thought this might work on these blocks if only I could remember what its called!!!!!!!!!
Any suggestions welcome

I wonder if you are thinking of a rag quilt. You join the blocks together using a 1/2 3/4 or inch seam on the right side then clip the seam allowance and put it in the tumble dryer. Hey presto all fluffy seams. I would try a small one first though as I think it depends on the fabric type you use. Good luck.

Here's what you're probably looking for.

also google quilt as you go. I am trying to remember where I saw a great tut on it.

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!

With rag squares, the batting is cut smaller so it doesn't show. Keep that in mind!

Sounds like it could be quilt as you go by adding sashing to the blocks as you put them together.

If all 3 layers are the same size, consider this method I have done with great success. Butt 2 squares togather, ziz zaz them togather, on the back side, cover with seam binding, can make your own and does not have to be on a biase. On the front do the same , I have used ribbon for this. Looks good.

did have a look at that but it will take alot of fiddling around as all the pieces are the same size and some of the quilting is close to the edge but thanks anyway

Yes thats the one will have to have a better look at the fabrics to see if they are suitable = thank you
