I'm sure it seems a little early to be asking this question, but when you consider that you may need to factor in learning and shipping times, it'll be time for holidays before you know it!
Please give yourself time and supplies to make a few batches of what you want to major and start small. Don't think you'll make a huge batch of lotions to give away the first time you try. As with everything good in life, it takes time and effort to get these things right. Start now and you may have something you're proud to share by December.
So what're you making? Do you need tutorials on the product? (First step, check out the newbie section of the blog!) Need some ideas for suppliers have you? (Check out the suppliers' section of the FAQ!) Anything else? Let me know!
