Re: Line from the hardware store?
Good to see people open to less expensive resources.
But you might also keep an eye on Milwaukee Rigging's Ebay store. They're always selling odd lengths of stayset (for sheets) and stayset-x (for halyards), often with eye splices, very cheaply. You can replace all your running rigging cheap if you watch for what you need. (I have no connection with them other than having bought there.)
