(20) 1 1/2" x 2 1/2" strips of Background fabric
(5) 1 1/2" x 3 1/2" strips of 4 Main fabrics
(1) 5" square of each 4 Main fabrics (Backing Squares)
(4) 5" squares of flannel or light batting (pre-wash flannel)
Use a 1/4" seam allowance unless otherwise stated.
Right-sides together stitch one main fabric to one background fabric on the short side. Do this for all 20 pieces.
Now stitch the opposite short sides together to form a tube.
It may seem a little weird if you've never used this technique before, but It will work out!
When you are done your tubes should look like this.
Now randomly snip the background fabric of your tubes so that they can open up and lie flat.
Tip 1: Use a steady hand so your fabric is straight and you don't have to trim off later -making a smaller coaster.
Tip 2: Cut at least 3/8" away from a seam line that way the background shows after the coaster is made.
Press your tubes open so they are strips. Press towards the dark.
(Missing Picture) Arrange your strips in 4 sets of five and stitch the strips in each set together to form 4 rectangles. (Should look like the right square in step 6 picture.)
Square up our rectangles to be 5" square. (This will require cutting about 1/4" off each first and last strip.)
Create your coaster sandwiches by placing your backing square and coaster top right-sides together, and then placing your flannel square on top of those. Stitch around all sides leaving an opening for turning at the bottom. Do this for all 4 sets.
Clip all your corners and turn the coasters right-side out so that the flannel is on the inside. Press flat with the seam allowance from the opening tucked in. Then using a smaller seam allowance top-stitch near the edge of each coaster to close it.
