My first full size quilt

I am currently working on a Bonnie Scotsman Quilt.  I am making it to cover a sofa bed.  It is approximately 87" x 77".   I have sewn it altogether and pinned it.  I am so happy I have a large DR table.  My husband put in the leaf and the pads and I pinned it on there.  I figured it would be alot better than laying it out and pinning it on the floor...and better for my back...
