I have the Marilee numbered pins (I think M*QC sells them) but I also have made my own. I purchased a box of pearl corsage pins then glued crystal beads with numbered and lettered plastic beads onto the pins. Some patterns refer to pieces by number others by letter so I use both. I prefer the homemade corsage pins as they’re longer and secure more pieces together. Plus they’re fun and pretty too! Great gifts BTW.
