The best way for me to describe this design is a big circle or ring. The outside of the ring has four panels and the inside of the ring has four panels. You can flip the ring so the inside panels become the outside panels. That's where the eight comes from. Four on each side. They are both made in the same way.
I made this quilt for a twin bed that is being used as a daybed where the quilt will drape down on each side.
You are essentially going to be making a very long quilt. I used an 8.5 by 11 piece of paper for my pattern. Easy. Two panels are made with 24 blocks and two panels are made with 16 blocks. There is also a border along the entire quilt. Repeat the pattern for the other side.
When both sides are complete, place right sides together and sew along the long edges. Start sewing about two inches in so that you can close up the circle. Now you have a long tube. Turn to the right side. I gave the whole thing a good ironing to get it nice and flat.
To close the circle, match up the correct sides. For the first panel you can use your sewing machine, but the second panel will have to be sewn by hand. I attached pictures of this to help, but for some reason I can't add image notes. For one side, you just sew with right sides together and then the second panel will just fold over the first.
Where you choose to fold the circle will determine which pattern will be prominently desplayed on your bed.
