How do you know how much fabric or how many different colors you will need?
Thanks

Here's a couple of sites that assist in calculating fabric.

Hope they help! :D

I only did one BOM and shopped in my stash.

The one I started, I picked 2 yards of 2 matching fabrics, and then I added to them out of my stash. This way I had some symmetry and the other fabric added interest to the blocks. My main fabrics had a lot of color choices to them, so it made it easy to add others.

Great advice Amma! I'm doing two blocks for each BOM.
1. I took from a couple 2 yard pieces of matching fabrics in my stash and added some complementary fabrics to the selection. 2. I have chosen one fabric (a neutral white on beige) to be my background in every month's block and then pulling from my scraps for each month. The unifying color being the background.

I am sorry but what is BOM???

BOM is short for Block of the Month

Dorrie, check at the bottom of the screen and you will see BOM. In that area are all the BOM's over the years. On the first of the month a new block is posted. You can jump in anyone at anytime. I've never done a BOM until this January--and now want to do other years. It's a great way to try new techniques, use up scraps of fabric or just put a 12 block quilt together one block at a time. Give it a try!

Thanks
