Whitney,

There is absolutely nothing wrong with this.

This is a wholesome, venerable, and time-honored tradition called "taking relics." We take and venerate relics of saints, even their bones since these have been known to work miracles.

Read the following passages related to relics:

• 2 Kings 13:20-21 (Contact with Elisha's bones restored life.)
  
• Acts 5:15-16 (Cures performed through Peter's shadow.)
  
• Acts 19:11-12 (Cures through face cloths that touched Paul.)
  

Rest assured, you are good, and may your mother's memory be eternal!
