*** "Do you know which accuquilt dies are going to be used for the 2012 BOM? I would like to put them on my Christmas list. Thanks."
Most of the applique shapes use my new Heather Feather dies (Heather Feather 1 and Heather Feather 2). There are also quite a few circles, which show up on various dies. Circle 2", 3" 5" would be a good one. Daisy has the 1.25" circles (of which there are a lot!). Round Flower has 1". Dresden Plate has 4".
*** "Does anyone know the type thread used yet? I want to use my Superior Thread coupon to purchase part of it."
I use AURIfil Cotton Mako ('cos it's my favorite!) in both 50wt and 28wt. You can use any thread that you like. The Superior Rainbows would be fun for the applique. Alex's Masterpiece would be good for piecing.
Hope this helps!
