Rod ring repairs

Hi everyone was wondering where everyone gets the rings, resin and whipping thread to replace rod rings? Ive found some on veals online but was wondering if anywhere in Ireland sells it. my local tackle shop only had cheap rings!!! thanks in advance for any info

i always just use normal sewing thread and nail varnish.
it may not look as professional as the originals but will still last for years and is pretty cheap.
also a thread holder used for fly tying is a must for keeping it neat.
