Repotting Question

[scy]

I recently repotted a phal from sphag to bark mix and am having trouble keeping it stabilized. It is currently in bloom and tends to lean after watering (stake and all). It is currently in a 5" plastic pot. How can I stabilize it if I do not have any rhizome clips? Are there any household items I can use?

I read in a different post that someone used rubber bands and I used that for a stabilizing my dendrobium, since the pot was small enough, but they don't quite work on my 5" plastic pot.
