Hold that thought, I may be back on.
What I wanted was Warcolours Red Glaze. They're in Cyprus, and it'd be nearly £10 to get from them due to shipping and there doesn't seem to be any UK sellers, so shipping time/cost was prohibitive. Plus a couple of other paints I couldn't find to order from the same seller as others I need were causing a time/cost issue - too much p&p, too many deliveries.
However I've decided to not use the Warcolours glaze as I think I could use Vallejo Red Ink + vallejo glaze medium. And I just found all the paints I need at a single e-tailer, so...
I've got some squigs + herders (2nd hand but still on sprue), the paints and some nice resin bases coming now. Just need to wait. All things being equal I might get just about 3 weeks to paint them...
