letter set with three patterns

I made a letter set of 3 original patterns that are a little retro. There are 3 types of envelopes and letter paper with matching patterns. The round part in the middle is made of tracing paper so that the address inside can be seen through. It is a pop assortment that makes the person who receives the letter feel happy. *set content* Envelopes (horizontal) x 6 (2 for each pattern), Stationery x 12 (4 for each pattern), Address cards x 6 ＊Materials＊ Both envelopes and letter paper use the back of kraft paper. It has a rough texture and a warm finish.
