I've touched on this hot topic in a previous post, but just how do you achieve that perfect balance of quality versus quantity? It'll be a different number for everyone but the answer is probably the same - enough that you enjoy posting and it's not an impossible challenge. If you have enough topics and time, then once a day (or even more) is perfectly achievable. If you're a bit pushed for time perhaps one post per week (or 2) will suffice.
In the past I've posted 3-4 times a week, but even when I was at home all day, I still found that a challenge. It takes longer than you think to construct a good blog post, especially when you have to find the right photos, resize them and upload them too. I've definitely underestimated the time involved before, and forced myself to post too often. If I still want it to be enjoyable and not a chore, I think once a week is about right for me. When I'm being super creative and making new items for my shop I'd probably post slightly more often.
How do you achieve that balance?
