Meg at olliegraphic recently designed these super cute custom invitations for a sibling birthday party... I think they're perfect for a Build-A-Bear Workshop birthday party!
Meg also created custom invites for Campbell & Charlie's reptile-themed birthday party last year (featured here on Oh My! Handmade Goodness).
These are two of my favorite custom invitations. You can view more examples of Meg's custom work here. Isn't she talented?!
If you'd like to commission Meg to create a custom illustration for you, you can then have it printed on any of the products that I offer through the custom section on my website. Please feel free to contact Meg or contact me with any questions!
