If you get all done and the quilt is not completely square or flat, some people like to block it. This is especially important if it is going into competition. There are many methods to do this. I myself like to wash my quilts before gifting and I get them out of the dryer slightly damp. I spread a clean sheet on the carpet and pin (rust-proof pins)any problem areas down as I block it. I let it dry in that position for a nice flat, square look before flolding. Some people like to just spritz a finished quilt with water and block it. The danger of that however is if the fabrics have not been pre-washed or the quilt washed, you could get a bleed.
