Favor boxes can be easily personalized these days. A lot of print firms offer this service at very reasonable prices. This may be something that your favor box supplier can organize. You can't fit many words on a favor box so, perhaps, just your names and wedding date will suffice. There is often the option to add a symbol to the box, a butterfly, love heart, wedding bell to name a few. For a little extra cost this can really make the difference between plain boxes and boxes with real flair!
If time allows and you have a creative streak, get busy with your glitter pen and write each guests name on their favor box. Not only will this add some sparkle to your wedding table but they can also double up as place cards.
Take care of the constraints imposed by the nature of the gift while packaging. For example, if the gift is made of glass, you need a holder inside the cage. It is elegant to use small dummy lanterns to hold small bottles of whiskey. If the box shield is opaque but the gift inside requires special care, it might be mishandled by the guests. Hence, the box or bag must not be misleading.
M&Ms are an ever-popular choice, because you can actually order them in any color you wish and include personal messages or names on them. Perhaps order M&Ms in your wedding theme colors with the bride and groom's names on each candy. After you have picked your candy out, put a few pieces into a little square of tulle and tie the top off with a matching ribbon. This is simple and easy to do, but always turns out really pretty! Other obvious wedding-themed edible treats are Hershey's kisses and conversation hearts. Mints are also a good idea, they are pretty and also provide guests with an after-dinner treat!
You may also prefer your boxes to be handmade to suit with your DIY wedding favors. If you have enough time and a flair for this, you can buy the required materials and artistically create your own wedding favor boxes.
