After the ceremony: Roll up your personalized aisle runner and bring it to the reception. As they announce the bridal party, you can walk down it again! It makes for another good photo opportunity!
More Ideas: After using your personalized wedding runner at the ceremony, display your hand painted monogram or special quote by hanging it up behind the DJ, head table, lay it in front of the "sweet table", or use it as a backdrop for photos at your reception.
When your wedding is over: You can cut off the design and have it framed, made into a banner, or design a quilt using the monogram to create a keepsake for years to come (pictured below).
