Adding shielding to existing cables

So I have some interconnects that are picking up all sorts of RFi. I know this for two reasons, one, as I move them around the noisy/buzz sound changes, and two, when I switch them out for shielded interconnects the noise goes away.

so, I bought some tinned copper shielding and some new RCA plugs. I’m going to cut the existing RCA plugs off the existing cable and install the new shielding and new plugs. The thing is the new plugs have a plastic body so there is nowhere to easily connect the shielding to ground.

I was thinking of running a pigtail from the shielding and attachIng an eyelet to ground it to my preamp since there is a grounding lug. Would this work or is there a better way given what I intend to use?

"Pro tip", good one. Tell 'em, pro, about your DIY cable skills. How about the "pro tip" where you discover your "pro cables" you built aren't even within 2dB of each other. 

DYODD OP. Read a few posts from this "pro" who is anything but. Draw your own conclusions.

Here is a great candidate.

The foil is a little better than braid at shielding.

@last_lemming,

You have a very nice system...I recommend using a better cables than DIY crap like Belden. I understand the urge of making your own cables but it’s not worth the trouble when you can have cables that not only sound great but also look aesthetically pleasing at the same price of DIY cables.

Look into Audio Envy IC’s, you can thank me later!

To be clear I have an existing Decware cable that sounds great, but is unshielded. I’m not trying to DIY a new cable from scratch. I just want to add shielding to see if that solves my noise problem. 
I have no issues with sliding a shield over the existing cable and grounding it to see if it fixes the issue. If it does then maybe I do a more permanent solution.
