I'll give you two options, with the trim and without the trim. The trim is a little tricky for beginners (even I cursed it to death) so I wrote out an alternative below for an easier and much quicker option.
1. You will need: a scrap of patterned fabric for the front, interfacing or felt for the interior, a soft fabric for the back, (I used satin on this one, and a super soft minky fabric on the pink one), a piece of elastic, a strip of fabric OR bias tape for the trim (optional). You will also need the pattern I made for you too. Just click here to open it in a new window, right click, then "Save Image As" to save it to your computer and print.
2. Using the pattern, you'll want to cut three identical pieces from each fabric.
3. Pin all three layers together down the center to hold them all in place.
4. Cut your lace to length. I just measure it half way around my head and make sure it's not loose. You want it fairy snug so it stays put. Place one end just under the outer layer of fabric. Pin in place. Do the same to the other side, making sure your elastic isn't twisted when you carry it over to the other side.
5. Sew around the parameter of the mask, about 1/4 of an inch or as tight to the edge as you can get. This just makes it easier for when we add the trim.
6. Time to add your trim. Place the underside of the trim underneath your mask...
7. Fold the remaining trim over the top of your mask.
8. Hold in place and sew the trim on. Go slowly around the bends as it does get a little tricky. When you come to your elastic ends, just make sure they are folded under nicely and not bent. You will be sewing right over the edges of them.
9. Finish and decorate with cute bows or other adornments!
This photo shows the super soft backing of my pink one. I also doubled up the elastic for a different look.
1. Follow steps 1 and 2 above.
2. Place your outer (patterned) fabric face up on your working surface.
3. Instead of placing the elastic on the outside as shown above, you're going to want to place it on the inside. We are making this one inside out. Attach the ends of the elastic in the same place as shown above in figure 4, only the ends of the elastic should line up with the outer edges of the mask.
4. Lay the backing piece face down on top of the first piece. The elastic is now sandwiched between these two layers.
5. Place your interfacing/felt on top of these two layers. Pin layers together as shown in figure 3 above.
5. Sew around the parameter as in figure 5 (remembering that this one is inside out though.) Be sure to leave a 2 inch gap free (i.e. don't sew the last 2 inches!). Keep an eye on your elastic inside of the mask, you don't want to mistakenly sew over it in a random place!
6. Turn the mask inside out through the hole you left (or is it right side in?! you get the point...). Stitch the hole shut and your mask is done!
