i also recommend you coordinate that fabric with others of similar weight.
use a 50-wt or 40-wt thread and a size 14 or 16 needle. if the fabric is all-cotton use cotton thread. otherwise, use polyester.
the bigger you make it, the more you'll have to wrassle with it, but that's good practice.
you might consider using it to make a duvet (which is just a fancy name for a comforter case) instead of a quilt. much easier to handle as it gets bigger but still very pretty and useful.
