How can I use these blocks?
 

I received about 60 blocks. They are all like the ones shown below. I don't know what the former owner had planned for them. What pattern could I use? I was also given more of the black fabric and also white fabric that has been cut into strips a little over 1.5" wide.
Any help is appreciated.

To me it looks like it was meant to be the "brick pattern."

Some sort of Shadow box quilt?? I have seen the instead of a square a rectangle. I think that MSQC has a pattern called Illusion???

I was thinking the Illusion also.

Same here or start of an attic window.

Are they about 4"x8" (including the black sashing?) If so, I would divide the amount into quarters and sew them together in groups of 15 to a row--sewing the black sashing to coloured body of the next block. Then cut 1.5" strips from the black and sew to one side of the first strip. Now sew the next strip to the sashing BUT turn the strip up side down--if you started the first row with the black at the top, start this row with the coloured at the top. Continue like this until you have put together all the blocks. If my initial size estimate was right, you would then have a throw that was approx 60"x43" before borders. It would look similar to Elise1's Passport quilt in this post except that it would
have the blocks going sideways.

oops just read what had been posted while I was posting and I agree with the two previous posters. The white strips would make a person lean towards the Illusions pattern.

You could simply sew them into strips, add 3 or 4 inch sashing between each strip and it would make an interesting pieced backing without too much effort.

Here's a simple idea - Put 2 of them together to make a square, trimming if necessary. Then lay them out however you like. I would probably alternate them.

I agree with Tartan. You are lucky to have received them.
