Hi, @Pilgrim
This is Max from the Shopify Team.
Have you had a chance to look at this coding tutorial - Add a gift-wrap option to your cart page? Depending on the theme you’re using this might be a good solution. I’d also encourage you to review this tutorial as well - Enable order notes on your cart page!

Let us know if one of these options suits, or if you need any more suggestions!
Cheers,
Max
