For any hobbyists selling their work you should consider registering with HMRC for an additional income under self employment and reducing your tax liabilities. If you do the figures right you'll make a large loss which you can then set against other income such as pensions or PAYE and receive a nice tax rebate. Never really understood why more don't do this as it's money for nothing
Well it's not completely 'money for nothing' there will be a fair amount of work needed in accountancy, whether paid for or DIY. That sort of paperwork doesn't suit everyone, especially if they're not used to self employment and the accounting issues that surround it. If you pay for an accountant, you may lose any profit too.
It's also possible that if you aggressively chase tax rebates you'll attract the attentions of HMRC and if they consider that you're not attempting to run a viable self employed business they're claim any rebate back, with interest, and possibly charge you for tax evasion.
First sell some stuff, if you can, then ask HMRC if you should account for it and how. They're actually very helpful if you play by the rules.
If you are thinking of trying to turn your hobby into a business, the important thing to do from day one is keep ALL receipts.
