1 1/4 yard worth of cotton fabrics for the top (you can do as many or as few different fabrics as you want)
1 yard fabric for the backing (I like minky which is just soft fuzzy fabric)
1 1/4 yard silky fabric for the ruffle
1 bag fiberfill stuffing (I use Poly-Fil)
Step 1: You're going to need two sets of squares: the top squares that make your bubbles, and the bottom squares that you won't be able to see. The top squares should be 6"x6" and the base squares should be 4.5"x4.5". Reminder: the base squares can be out of any old fabric you have lying around because it doesn't matter what they look like because you won't be able to see them. You need 49 of each.
Continue pinning each of the four corners together.
Then fold it down so that you have and s shaped pleat centered between the two pins. Pin it in place.
Repeat on all four sides.
Continue until you have all 49 of the squares finished. Lay them out in the design you want your blanket to be.
Assemble your top just like you would any quilt top, piece by piece. Make sure to keep them in the order you want!
When you get to sewing bigger strips of them together, put in pins at the seams to help keep things in place and to give yourself a nice even top.
Continue until your entire top is pieced together.
All your pieces should be flat and deflated.
Now cut a slit about 2" long in the bottom square fabric.
You want your slits to be cut diagonally along the fabric to prevent fraying.
Once all the bubbles are stuffed, you're going to have to hand stitch up each one of those slits. Arg! I know! Just pop in a movie and power through, it's so much easier than the first method even if it does take longer. I double thread my needle for extra strength.
Cut out and make your ruffle. See my tutorial here to learn how to make one. Take your ruffle and place it on the backing (which is right side up). Line up the raw edges of the ruffle with the edge of the backing and pin in place all around the square.
Sew the ruffle in place with a 1/4" seam.
Place the backing with ruffle right side down on top of the bubbles. Tuck the ruffle inside so you can't see any of it.
Pin everything together and then sew around. Be very careful not to snag the ruffle in the seam during this process. Just go slow and stick you hand in between the pins to straighten the ruffle as you go (see tip below). Leave a fairly large opening for turning the blanket right side out, mine was about 7" wide.
I find it useful to use a zipper foot for this part of the project. Also, when I get to a corner, I pull the fabric like so and stop at the corner
and then shove the ruffle back inside out of the way when I turn the corner. You can watch the video here for a better explanation. The pertinent part starts at about 17 minutes.
Once you go all the way around you can turn the blanket right side out and then last but not least, hand stitch up the opening.
You're all done! Enjoy your amazing new bubble blanket!!!
