attaching & trimming java moss

[pckroeger]

I am very new to live plants, what do you use to trim/prune plants like java moss and riccia??
Also, I am tying the java moss to a DIY pvc pipe cave that has sand glued to it with silicone, how long should i wait until it will be secure enough to remove the cotton thread?
thanks :)

Small scissors, preferably stainless steel. About 6 weeks should do it.
