Step 1: Basic Supplies
You can choose to use cotton fabric or flannel. If you choose to use flannel you won't need the batting. If you purchase your fabric as charm packs you have no need to cut your fabrics since they are pre-cut.
You will, however, have to cut your Warm and Natural.
For the batting I prefer the Warm and Natural because you don't have to quilt very close, and also because I have seen a picture of a quilt dried in the clothes dryer that has scorched because of using the 'cheaper' so-called natural batting. It is needle punched and won't pill or bunch. (Nope, they aren't paying me to plug their product!)
Your fabric requirements:
To start small, a good sized baby blanket will be 10 x 12 squares.
10 X 12 = 120 squares.
BUT you have to double that number because this is a quilt-as-you-go and you need a front and a back.
So you need 240 of the 5'' squares.
IF you want to cut the fabric yourself I found that I was able to get 15 squares out of a fat quarter.
240 divided by 15 = 16. So you need 16 fat quarters or 8 half-yards depending on how much variety you want in your quilt. If you sew already you may have a stash you can raid.
Now, if you are *not* using flannel you will need to cut 1 - 4'' square of batting for each quilt square. So 120 of the 4'' squares. I can get 90 squares out of a yard of batting, so I would need not quite 1 1/2 yards of batting.
Each square will finish at 4'' because we use a 1/2'' seam allowance.
I also used a walking foot on my machine. It helped immensely. If you don't have one, or don't want to use it, you may need to use more pins than I did.
