This takes hardly any time at all. The planning of the size probably takes the most time, and making sure the letters are the right size takes a few minutes as well. All together - maybe an hour?
Using a cheap frame ($1), and having the back be too flexible.
What made it easier:
Deciding to go with the smaller size - 5 X 7 for this one.
The Cricut machine - gave me the perfect size for the J & B.
The heart punch I already owned.
Short song lyrics - thanks, John Denver!
