I have finally worked out a way to do a reversible quilt as you go quilt on the sewing machine without any ugly mishaps and problems. I am sure other quilters have done it before me and probably even better but here is how I did it.
All the blocks, both front and back, are the same size and ready to be assembled into strips. The quilting has been done in a sort of spiral pattern.
The sashing on the front is 1 1/4 " wide in Kona Ash and the sashing on the back (Kona Snow) needs to be bigger, so I cut it to 1 3/4 ".
I pinned the 3 layers together with the Ash on the front.

... and the Kona Snow on the back.

and here is the triple sandwhich pinned together.

now I sew along the edge with a proper seam allowance.

then I pin the other side of the Ash sashing on the top to the edge of the next block and sew along the edge again.

turning the two attached blocks over looks like this.

and this it what is looks like on the back.

now I fold over the Snow sashing on the back along the seam and iron it flat.

and then I fold it over again to cover the seam on the next block.

pin the 3 layers together to fix the sashing on the back in place.

and I sew closely to the edge to attach the back sashing firmly.

the I sew along the other edge to make sure it looks even.

et Voila. this is what the 2 QAYG blocks look when attached this way.
on the the top

and the back.

I hope this makes sense.
Love, Nadine
