I've just found out that Hilde is re-running the workshops, called Pwyll, Rhiannon and the Spirits of the Land, and I would thoroughly recommend them if you missed them the first time round.
There are four workshops in the series:
Entering the Otherworld, on Saturday, 17 April
Otherworld Beloved, on Saturday, 5 June
Otherworld Child on Saturday, on 7 August
Rhiannon, Mare of Sovereignty, on Saturday, 2 October
The description of the workshops on the Deertracks website says:
"Through the story of Pwyll and Rhiannon, this series of workshops shows you how to bring harmony to your life and your world by forming an intimate relationship with Spirit. That way trust can be restored between humans and the spirits of the land, and gifts can flow freely between the worlds once again."Each workshop runs from 11am until 6 pm and the cost is £40 per workshop or £120 for all four if you pay for the whole series in advance.
The workshops take place at a quiet location in Harrow & Wealdstone, which is just north of London, 15 minutes by train from Euston.
