Anyone else here discovered Washi tape - just ordered some after seeing an online review and it's the same stuff pretty much as Tamiya masking tape but you get 20 rolls for around £12.00 GBP. (Make sure it's from MT - there are other cheaper variants which are not as good)

Had order direct from Japan though. Apparently, (I've only just discovered this) Washi tape can commonly be found in your wife's craft box, especially if she's into making stuff like cards/calendars/Planners etc.

(Thanks love - would have saved me the trouble had I known!)
