Containing all those leaf hops?

Currently I only do one or two hop additions when brewing and I use some nylon bags with drawstrings that I tie shut and throw into the boil. Since i'm using leaf hops this keeps the mess of hops cotained in the bag.

On my last brew a bag worked itself open and all the hops came out which resulted in a clogged ball valve and a mess trying to get all the beer out of there.

My next brew I want to make has a lot of hop additions. How should I handle this? I don't really want to throw in a dozen bags of leaf hops(I can, just seems like a lot of cleaning afterwards) and would like some good reusable options. Thanks!

I did an IPA today with 4 oz whole leaf hops and I just threw them loose in the kettle. After I chilled I wrapped my auto siphon in a paint strainer bag and racked to my Carboy. Worked great - all the hop material stayed in the kettle. You just lose a bit of wort in the kettle to the hops.

It does NOT work with pellet hops, but it works so great with leaf hops! The hops just go in the boil, and then I open the ballvalve and the hops stay in the kettle, and strain out the hot break as well by forming a filter on the screen. Hops pellets will clog it right up though!

I made a hop spider out of a pvc coupling, four inch I think, and a wooden dowel rod. I attach a5 gallon paint strainer bag to the coupling worth a big hose clamp and add my hops to that. Works worth lead and pellet. The bag doors get heavy with big leaf brew says
