Sent to Natercia Tomé (France).
Collage for the project Fenêtres. I used windows cut from a catalogue of hotels, and I also decorated the envelope with colour pencils. I like the collage, but I am not sure if the envelope is really nice or matches with the collage.
Natercia makes three mail art calls in her blog (les folles enveloppes): windows, benches and green.
