Lost stakes are not a problem for me. I put the adjustment or tensioner on the tent/tarp side of the guy line and attach the stakes to the guyline with a clove hitch. The stake generally stays attached to the guy line even when dislodged.

The side benefit is that it cleans the stake when I slide the clove hitch off the bottom.
