Specific White Background

[jl44]

Hi,
I would like to use this graphic as a background for my wedding invitations, and I was wondering if someone could help me change the color of the background to just white (or remove the background color completely, whichever is easier). I would greatly appreciate any help possible!

Thanks SO much!!
