I too have just finished 2 quilt tops for my granddaughters for Christmas presents and am ready for the ever terrifying sandwich.

These are twin sized quilts and I will be just doing the SITD, BUT what I don't know is the approx. amount of time I will need to quilt each of them. The blocks are 12 X 12. 4 hours? 8 hours? OMG longer?

Just need a ballpark figure for this newbie who is also using a walking foot (oh goodie) at medium speed on the machine.
