These coasters are machine wash and dry friendly (they shrink just a little) ... and no matter what fabric you use: French inspired, modern, novelty, floral ... they look great.
Total items needed are (5) squares 5"x 5" and a piece of fusible fleece 4" x 4" or scrap batting for each coaster.
Put the fusible fleece, fleece or batting on the back square for more padding. A little spray baste will adhere it if you don't have fusible fleece. No spray baste? Just sew an "X" through the fleece/batting on the back square.
The reason for this is so your batting/fleece will latch onto the back and not move.
Iron the 5" squares into triangles and assemble as shown above. Triangles lay on top of each other and the last triangle goes beneath the first one (pic 4). You are kind of weaving the triangles all together.
If you have a design element you want to see on your coaster - do steps 1-4. I wanted the coffee cups to show on the front of my coaster - so here is how to achieve that.
(1) slide a piece of cardstock or paper plate under your coaster pieces.
(2) put another piece of cardstock on top of that
Now flip everything over - like you are making pancakes.
(3) Lift off the cardstock and what you see is the BACK of the triangles. That's what you want. The coffee cups I want to highlight are facing down, not towards me. They will appear after sewing since you are going to turn this whole unit inside out!
(4) Nestle everything tightly and pin so the triangles don't slide around (they will!).
(5) Move the pinned unit on top of the right side of back square (the one with the batting) and pin everything together (6).
(1) Sew around the edge of the coaster using a 1/4" seam and small stitches. I usually sew off the coaster after each side but do a few reinforcing back and forth stitches at the corner area. Neatness does not count! Remove pins.
(2) Trim sides and just take a little off the corners.
(3) Dig into the center of the coaster and start to turn it inside out.
(4 - 6) Keep turning it inside out - poking the corners with a chopstick or something pointy.
Lastly - its personal choice whether to top quilt them - I say 'yes' as they tend to flop & not look finished. How to do it in one continuous line is shown (a little rustic) below.
