If you don't want to make your garland cages with chicken wire, you have some other options. First is egg shaped cages. They also are available in round as well as the oval shaped cages. They do not have florist foam, however, so you will still have to buy brick foam and trim to fit inside the cages. They are available in two sizes, so read the descriptions carefully to choose the ones that fit your needs the best.
The next option is Oasis Garland. It comes in two separate shapes. One is cylinders and the other has a flattened back for table top garlands. Oasis gives us florist foam in lightweight netted bags that hold the foam and keeps it from degrading, yet allows us to push flowers into easily - wrapping them around almost anything!
Cut apart and hang from bridal chairs or wedding pews. Lay them on church window ledges. Drape as garland from outdoor wedding gazebos. The design possibilities are endless.
They seem expensive - but the 9 foot garland comes with 14 cylinders (think 14 pews or chairs!) and the 32.9 ft has 50 cylinders. These are the longest and largest of the cylinders. I have used these garlands myself and they have beautiful results with the least amount of work on your part.
Bright Creations also offers a 12 piece garland prefilled with wet florist foam, meaning you can use it for either fresh or silk flowers. I have not used this brand myself, but I caution you against trusting the plastic hooks. Wet foam is heavy, so I would still secure the foam cylinders together with chenille stems.
