Thank you so much for the encouragement and more information. This will not be a wall quilt. As with all of my quilts this one is growing by leaps and bounds! The photo has it displayed on a double size bed and it's still missing the bottom right corner!
Bree, thank you so much for your comments. The muslin is a good quality from the local quilt shops. The black and the colored squares are Moda's Bella. I am going to wash one of the bella squares today and see how much it shrinks. Just for the heck of it!
After reading the above comments I will probably use a polyester batt. Ordinarily I like the 'antique crinkling' look but I don't think that's what I want for this more modern quilt. I'm anxious now to see how this whole experiment will turn out.
I always want to be sure the quilt is perfect for my grandchildren but especially for this grandson. He's already bragged to his brothers that his quilt was going to be much better than theirs! Now I've got to live up to this? LOL
Thank you all so much! Your help is appreciated more than you know!
