Yes....tie it! That will solve many issues with quilting after putting the binding on. But the spacing between the ties will be dependent on the batting used. Unless you have the packaging from the batting to tell you the recommended quilting/tying spacing (or remember what exactly you used and can find it again) I would put the ties fairly close, probably 3-4 inches apart. With all the work you put into the quilt, you certainly don't want the batting to fall apart inside the quilt! Very nice quilt....bright and cheery!
