Buttonholes Without a Buttonhole Foot

I am attaching 2 giant buttons to my latest project, and they are too big to use my buttonhole foot for.
What to do?
Google.

I found this great video tutorial on how to do it freestyle. The part you want is at around 7 minutes into the video.

It was a little stressful since I couldn't take my foot off the pedal and had to tap the buttonhole thing at exactly the right moment, so I had to distract the girls with suckers and 2 minute tasks to keep them away while performing my buttonhole surgery. It turned out great!
