I hosed them down in the shower to get rid of all the sand and crawlies and then leant them up against the radiator to dry...which took weeks. About a week before christmas tom got to work finding dowels. He made two lead dowels for weight which he slotted down into holes he drilled in the base...and then he drilled down the lead dowels to add wooden ones that would hold the upright of the bookends in place.
We went to the beach somewhat doubting that we'd find any driftwood at all...but look at our spoils! It was pettycur bay we visited, in Fife, and despite it being a scottish November, the sun was shining and with all the rock hopping and digging, we soon warmed up :)
