If you are unable to move an embellishment within your design, it’s likely due to it being locked.
Click on the “+” symbol located in the Embellishment panel on the bottom-left side of the design center.
This will open the Embellishment panel. Find the embellishment you wish to unlock. If a lock symbol is visible in the bottom-left corner of the embellishment thumbnail, then the embellishment is locked.
Click on the lock symbol and it will unlock — allowing you to move the embellishment around as you please.
