The next group are cards that have had glue used on various parts of the card plus the greeting and then while still wet it is covered with minute particles of colored material that adhered only to the glue (this was called tinseling). Most were done when the card was made, but it looks like some of them could have been done by the person sending the card. These are also called glitter cards, (at least by me).
Felt used for flower.
