Are you looking to establish dedicated safe places for him to land?
If so, that can be a long list of things: boings, orbits, play stands... their cage.
When starting out, he may land on your countertop/table/sofa or other large solid-looking surface before he has the precision control to land on smaller spots.
One of mine still prefers to land on me if he has a choice in the matter.
(be mindful of windows and window coverings, doors, sinks, toilets during this process)
... oh yeah, for nets, I really like Aronico, but I wouldn't consider them cheap (although they'll last a lifetime with your little ones).
