It is reversible with the exact same fabric on the back as on the front. It was made using these instructions from Quilter's Newsletter Magazine, July/August 1998.
Each block is essentially a four-patch folded on the diagonal of each square. A square of batting is inserted before the last seam is sewn. Then the each block can be quilted and then whip-stitched together to make the quilt.
I revisited the quilt and the process described above in preparation for a demo. While I made the demo block I decided it would become a small mug rug or coaster. (I 'm not too keen on whip stitching a bunch of blocks right now, though it would make a cute quilt.)
That thought led to the idea of making sets of 4 blocks which I could then give as gifts. Consequently, I cut 360 - 4.5 inch squares from dark blues and shirtings which have occupied my stash a bit too long. And for the same project I cut from batch of odd sized batting, which had been put aside way back when, 80 - 5.5 inch squares.
Not done yet. I've learned that once I get going with a boring task like endless cutting, I do better when I get as much of it out of the way for multiple projects, rather than complete one project and then go on to the next. So almost as soon as I finished the above cutting, I decided that I needed new hot pads in the kitchen. I had a stash of "food" fabric that was "getting old". So I've cut that up along with some more batting and insul-brite. I am glad to have that cut and ready for action! The extra hot pads will go into my gift drawer, too. It feels good to have found a way to use fabric and batting that has been lying around too long.
