Hi Helen,
Pricing is a tricky one - we all want to make our prices fair and affordable but also make a profit so that we can keep going! I just had a quick look in your shop (very clever and admirable use of recycling!) - I think your prices seem fair but if you wanted to you could raise them up a bit - I'm thinking of that mindset most of us have 'you get what you pay for' and your items look to be well made with care and attention to detail.
Hope this helps and wishing you all the best :)
