I need to donate a craft for my church's Harvest Fair - they will sell them. I didn't want to do anything too expensive on my part. I came up with halloween luminaries. I used orange gift bags and black vinyl. They glow so beautifully. I will package them in 6 mixed designs together.
You could also use black paper and glue the design on if you don't want to use the vinyl, but I figure these are reusable as well because the bags are pretty sturdy. You could also use white or kraft bags.
To expand on this idea, they would be great for an evening wedding with wedding bells or a monogram on them.
I also thought they would be cute to spell out a word like B-O-O, one letter on each bag, or anything for that matter
