I think your wonderful quilt and quilt top may be overlooked to some extent in the hubbub of the shower. It may be more special to present them after the babies arrive. You already have gifts for the shower and you've already heavily contributed in labor, love and supplies to it as well.
Now, if folks will be there who may not see the quilts later, that would be another consideration.
Now, try to be kind to yourself. You've gone above and beyond!
