Bulletin Board

My friend Marta asked me for instructions to do this bulletin board...here they are :

(Marta, perdona que esten en ingles...hace un tiempo una amiga me las pidio, y se las mande en ingles, pero si alguna o alguno quiere hacer este "corcho", y no las entiende o las quiere en español, decidmelo y las traduzco en un "plis-plas", ok???)

Paint your bulletin board (with normal paint) with a neutral color that matches the one* (spray paint) that you want to use for the lace pattern (*this is the color that it's going to all over your bulletin board. I did mine in black)
Let it dry, and then, buy some cheap lace curtains in Savers, or D.I. or some place similar, and staple it to your bulletin board, very close to the edges (you will remove the staples later, but the lace fabric has to be very tense).
Spray the bulletin with the spray paint, be very generous. The more you spray, the darker the color will be.
Let it dry for a day or two, and then remove the staples and the fabric, and...tada!!!!!!!!!!!...
