Memorizing Scripture

Happy hump day.  Greg and I have been talking lately about memorizing Scripture.  We both can remember general areas of where things are but we are both terrible at memorizing verses and passages.  We have decided to work on this together and to commit the Word of God to our heart.  

What ways have you found that are most effective to memorize Scripture?  In the past, I have written out a verse or verses on index cards and carried them around with me.  I would pull it out and review it throughout the day.  I also like using the She Reads Truth lockscreens on my phone.  We are open to suggestions.
