I love the pattern you picked out. It does have a lot of seams, but is doable. If it were my quilt to quilt, I would quilt it 1/4 inch from the seams, then you don't have to quilt over seams or through multiple layers.
1. Use silk batting. It needles easily.
2. Use a size 10 Hiroshoma Tulip betweens needle. They are sharp, never bend, and glide through the fabric.
3. Use quilting thread. I like YLI brand.
4. I don't use a hoop, just lap quilt a small baby quilt.
Most important. Make a small quilt sandwich with the same fabric and batting to practice on. You will find out if this is something doable for you. You could also try out big stitch to see how that works for you. I haven't done big stitch, so don't know what kind of needle to use, but it does look nice.
