What about if you used Microsoft Word or some other program and made her coupons? Like, "This coupon is good for 5 hours of uninterrupted quilting time" "This coupon is good for a trip to the fabric store on me" This coupon is good for me cooking dinner...
My hubby did that the first year we were married and didn't have any money, and it was great! I saved all the coupons in a dollar store photo album. You can make them anything, you cooking, cleaning, helping out in her sewing room, etc!
