Someone needs to sell buttons in bulk for cheap. Doing projects like this is hard to do otherwise. We went to four stores and still had a hard time finding a selection of buttons in different shades of pink and red.
Luckily it all worked out. Spent an afternoon meticulously lining up buttons to make hearts on a black canvas and then hot glueing them down. Looks great and I can’t take any credit, I didn’t do it. I have very talented friend.
