This is the biscuit or bubble quilt, or as many of my friends call 
it, the boob quilt. There's a few different ideas of how to do this, 
mine have simple pleats on each side with an 11cm base. Enjoy!
|  | 
| Cut
 out 15cm squares in the colours you want, these will be the top of the 
quilt (A rainbow or random patchwork design or similar works well, 
google will provide inspiration. My quilt had 9 squares in each of 7 
colours). Cut the same number of squares in a scrap fabric, 11cm wide | 
|  | 
| Pin a small square to the WRONG side of the large square at the corners. | 
|  | 
| On each side, make a pleat roughly in the centre |  | 
 | and pin. repeat with each square | 
|  | 
| Sew pinned sections together, and the ends of the rows. | 
|  | 
| When
 you've got a whole row of squares pinned, place 2 pleated squares RIGHT
 side to right side. Repin pleats together and pin at the corners as 
well. | 
|  | 
| Sew
 all pinned bits together, and the ends of the row pleats need to be 
sewn down as well. For the FIRST row only, sew along the bottom, closing
 each square on 3 sides and sewing the pleats down. Repeat with the next
 row, NOT sewing the bottom. | 
|  | 
| Pin
 the next row of SEWN squares to your first row. I tacked the pleats in 
row 1 together, which made stuffing easier. Then pin the first and 
second rows together at the seams and at the pleats. | 
|  | 
| Stuff! When you finish stuffing a bubble, pin your heart out to attach the bubble to its backing and the next row. | 
|  | 
| Sew
 the very pinned stuffed bubble to the unstuffed bubble row. It gets a 
bit fiddly, but I managed with a normal foot and 3/8th of a inch seam 
allowance. | 
|  | 
| You
 should end up with it looking something like this. I missed a little 
bit of the fabric once or twice, but went over it again quite easily. 
Repeat this for every row, you may need to go in stages if, like me, you
 have a limited supply of sharp pins. | 
All
 in all, I found this worked very well for me. When you get to the last 
row, you just need to sew it all up without sewing it to another 
unstuffed row. You should get a lovely quilt top of bubbles and puffy 
stuff and they are so much fun to squeeze! Any questions/problems etc,
