Preparing the Fabric

No one likes to hear this part (least of all, me), but when we have brand new fabric, there’s a strong possibility it will shrink when washed. Since these cute, adorable coasters are going to be catching coffee and tea drips, we will likely want to wash them later … which means we should really pre-wash them now.

When I have to pre-wash fabric, I like to do it the night before my project so the next day I can jump right in to the fun part: cutting and sewing!

These coasters are easy to cut: I cut long strips of prewashed fabric, then use a smaller ruler to cut the 5×5 and 3×3 square pieces.

Step-by-Step Tutorial: Sewing Patriotic Fabric Coasters

Step 1: Prepare the Blue Star Square

Take your 3×3 inch blue fabric square with white stars. Turn under approximately 1/4 inch of the fabric on two adjacent edges (not the outer edges that will be sewn into the final seam). Press these folded edges.

Step 2: Attach the Blue Star Square to the Ticking

Position the prepared blue star square onto the top left side of your 5×5 inch red and white striped ticking square. (Position the stripes horizontally to mimic the flag.)

Pin the folded edges of the blue square to the ticking, just to hold it in place for sewing.

Stitch these two folded edges down, about 1/8 inch from the folded edges.

Step 3: Layer the Fabrics

Align the flannel square with the red and white ticking fabric (which now has the blue square attached), right sides together.

Pin or clip the two squares together, if you like, to hold them in place for sewing.

Step 4: Sew Around the Edges

Using a 1/4 inch seam allowance, stitch around all four sides of the layered square. Remember to leave about a 2-inch opening on one side for turning.

Backstitch at the beginning and end of the opening to secure the seam, since this is where you’ll be turning the fabric.

Step 5: Trim the Corners

Carefully trim the excess fabric at each corner diagonally, being careful not to cut through your stitching. This will help you get sharper corners when you turn the coaster right side out.

Step 6: Turn Right Side Out

Gently turn the coaster right side out through the opening you left. Use a point turner, a crochet hook, or the end of a pencil or pen to carefully push out the corners and make them sharp. (If your point turner is too sharp or you push too hard, you could end up poking a hole in the corner. If that happens, just turn it wrong side out again and re-sew that corner.)

Step 7: Press Your Coaster

Use your iron to press the coaster flat. Pay special attention to the opening, folding the raw edges inwards by 1/4 inch and pressing them in place.

Step 8: Topstitch to Finish

Topstitch close to the edge (about 1/8 inch) all the way around the coaster. This will close the turning opening and give your easy 4th of July sewing project a clean, finished look.

Try this

Take your coasters up a notch with decorative topstitching (maybe even in metallic thread), or swap in denim or canvas for a rustic farmhouse feel. Another alternative is to make an American flag mug rug by elongating the red and white ticking.

Step 9: Repeat for a Festive Set!

Repeat steps 1 through 8 to complete the whole set of easy patriotic star coasters for all your Memorial Day, 4th of July, Veterans Day or other Americana themed gatherings.
