You have all the time to rearrange or polish your flower arrangement. The flower design should look beautiful and artistic enough before you place your filler, when the filler is already placed, it would be harder to move your things around the area or place. Bear in mind that The filler are very fragile.
An individually designed flower bouquet makes for an ideal gift as it is thoughtful with a personal touch. Keep in mind whom the bouquet is being created for. The tone of the bouquet is largely determined by the colours you choose. It would be preferable to choose the receiver's favourite colour as theme for the arrangement or bouquet.
