Due to many negative reviews from clients who purchased set of 3 arrangements or 1 large and 1 small arrangement, we decided to not sell them in packages, only separately. Yeah arrangement will be packed in separate box. The size of large arrangement is about 40" length and about 20" width, smaller ones are overall 22" by 16-18". Colors can be changed, removed or substituted for other colors. Each arrangement has 4 zip ties on the back to help you attach it to your arch. Hooks can be added on your request! Please feel free to leave a note for any additional instructions! If you have any question or you would like to make a custom please feel free to contact me!
