[Not really “make” your own gear. Rather “modify”…]
My tent (Nemo Hornet) uses small velcro tabs in order to secure the fly to the pole set. I practically never use them (i.e. I just drape the fly over the pole set), largely because I’d have to spend an inordinate amount of time to set/unset the tabs.
So the plan is to semi-permanently attach clips, similar to those used to secure the body to the pole set, using the velcro tabs. Leave them attached to the fly and clip the fly to the pole.
I assume that plastic clips are benign addition, since they are used to secure the tent body. However, when I asked Nemo about sourcing clips, their reply suggested that this wasn’t a good idea and would void the warranty — I believe they assumed that I would the fly if I were to glue of sew clips.
Anyhow, if you have wise words for me, I am all ears.
