I made these easy Christmas Tree Napkins for everyone at our extended family dinner last year. Each guest had their own unique napkin to take home. The napkins were so popular that I decided to share the technique for making them in this instructable.

Step 1: Supplies

You will need:

1/2 yard each of two coordinating cotton or cotton/polyester prints
scissors
a pencil
a large piece of paper for the half circle pattern
access to a sewing machine and iron

This amount of fabric will make four napkins.

Step 2: Make the Paper Pattern - a Half Circle

I found a great technique to make a circle or half circle at this instructable, using two pencils and strip of cardboard to create a compass. Put the pencil which is the fixed point eraser side down and draw the arc of the circle with the other pencil. The two pencils go through holes you have made in the cardboard, 9" apart.

Using this technique, draw a half circle with a 9" radius on a piece of paper as shown in the photo.

Cut out the half circle.

This will be your pattern.

Step 3: Cut Out Half Circles on Both Pieces of Fabric

Place the two pieces of fabric right sides together so you can cut both at the same time.
Place the paper pattern at one long end - it should just fit - the half circle is 18" wide, which is exactly 1/2 yard.
Pin the pattern to the fabric and cut out the half circle on both pieces of fabric.
Remove pins, and use the pins to hold the two pieces of fabric together.
On the long straight edge, pin to mark an opening, approximately 3" wide, which you will use to turn the napkin right side out after sewing.

Step 4: Sew the Two Pieces of Fabric Together

Using a 1/4" seam allowance, sew the two pieces of fabric together, right sides together, leaving an opening of about 3" between the two pins.
Backstitch at the beginning and end of your stitching to secure the stitches.
Trim the two corners diagonally, to reduce bulk. (The corners will turn better if you sew one diagonal stitch at the corner.)

Step 5: Turn Napkin Right Side Out

Using the 3" opening, turn the napkin right side out.
Use a chopstick, knitting needle, crochet hook or other pointy stick to push out the corners neatly.
Press, being careful to push out all the fabric from the inside at the edges.
As you press, press down the 1/4" seam allowance on the 3" opening. This will be sewn down by the topstitching.

Step 6: Draw Fold Lines

This is where the magic happens! It's the off-centre folds that transform the half circle into a tiered Christmas tree.

Draw a line 1 1/2" away from the centre radius line using chalk or an erasable marker, perpendicular to the horizontal edge of the napkin. (This is the red vertical line in photo - I've marked it on the paper pattern in the photo for ease of viewing)
Fold each side in to meet this off-centre line - see red lines in the photo - and press these folds.
Mark these two fold lines with chalk or an erasable marker. Or you can simply use the pressed lines as your marking if you are confident that these will be clear enough to guide your sewing.

Step 7: Fold Along Lines to Create Tree

Fold using an accordion technique along each of the three marked lines, to create the tree shape, and confirm that your lines or folds are in the right place before topstitching.

Step 8: Topstitch Napkin

Topstitch close to edge to secure napkin edges (including the 3" opening you left for turning), and also stitch along the fold lines. This will prevent the two layers of the napkin from shifting when you wash it and will also remind you how to fold the napkin.

Start and end with a few short stitches to secure the stitching line. The photo shows a path for topstitching in one continuous line.

Step 9: Fold and Press

Fold along the stitched lines, and press the napkin.

Folding in one direction reveals more of one fabric - you can fold it the opposite way to reveal the other fabric. One napkin is the reverse of the other.

You have finished your Christmas tree napkin!

Step 10: Creative Variations

Even though you have marked and topstitched lines for 3 folds, you can still fold your napkin in different ways.
For example, you can fold in slightly less fabric, and make 4 folds rather than 3, for a skinnier, more tiered tree.

You can also add a trunk to your half circle pattern, as in the red napkin above. If you add a trunk, you will have to stick to the 3 marked folds, as folding it differently will make the trunk off-centre.

You could also sew trim to the outer curved edge on one side, to create the effect of a garland hanging off the tree.

Enjoy and share!
