If you want advise, here's mine: if you are new to quilting, don't start with two king size quilts that you don't know how to put together. I admire your vision, but I have found that nothing kills your enthusiasm faster that an overwhelming project with problem after problem. I'd make the dream catcher blocks into pillows or a wall hanging, and use a simpler pattern with precise instructions and directions for your quilts. Also, hand embroidered blocks don't seem like they would stand up well for 2 boys on a bed. Again, I admire your vision, but this is just my advise - since you asked!
