You will need to cut the flower stems to a manageable length for carrying on the wedding day. Don't do this until the Bind-IT tape is securely fastened and the stems are secure against the bouquet handle.
I use professional floral snips (also known as "bunch cutters"). The heavy duty blades easily cut thru the stems and branches. If you don't have snips, use a sharp knife or kitchen shears. You don't have to worry about crushing these stems, since they aren't really pulling up water to the flower head.
Leave a little extra length if you're not sure how long the bride would like to have them stems. You can always cut off more - but you can't add it on!
Note the slight outward flare that I worked to keep. However, the stems are clean, bound and look just like the real thing.
