Here's a cool holiday prop frame that Matthew shared in the Facebook group. Check out the link below to see some cool 3D printed mounts that he referenced and used to attach the lights etc.
"Meet Henry (my niece named him) from EFL Designs . Maker Pipe makes him stand proud. Also used, 3D printed mounts from Inspire Light Shows . I may add a sandbag to the base in addition to the spikes."
