You may end up happier if you try to mark a spot in the seam allowance, at the same place on each of your mirror blocks. Pencil, removable or pigma permanent pen? Put down one of each and match each block to one of them to sort them after confusing yourself? So much fun, all the best.
That is cool(Baby Boomer talk) I just ordered these templates. I would make a whole quilt with that big star and other pieces in different fabrics and sash each block..
You can make anything with scrappy blocks, from small gifts to huge quilts, or even curtains. 8"×16" is two blocks, add some borders with one or rwo wider ones at top and/or just bottom, to get the shape? Play with them, try contrasts, or get a wide bit for on the top left and lower right? You could use half of a finished block, for each strip, to keep it scrappy? Try one left or centered block and add wide side borders and base? You can put one pocket to halfway up on the right for cutlery, or a flower? What about a napkin too. You could put in a heat shield (for pot mitts,) to save your table, if you won't need to wash it much? See where your mind can take you? No quilt police zone, so have fun. All the best.
