Here's an idea for anyone who has spent longer getting the flaming jam labels to print out properly than they spent making the jam in the first place. Aren't these labels brilliant! Just create a full page of "blackberry jelly" (or whatever) repeated over and over in a pretty font and colour. Then run your sheet of labels through the printer with complete disregard for the label boundaries or careful positioning of the text.
Sadly I can't take credit for this excellent idea. It's from Mrs Nesbitt's blog. I'll certainly be making use of her great ideas on presentation.
