Thanks for all your replies...certainly food for thought. My worry about only commiting part-time to it is not being able to generate enough stuff to fulfill commitments with a shopping site (I've previously worked freelance as a textile designer and struggled sometimes to come up with my quota of work - despite time constraints I also hate having the pressure of having to produce something, even if it's not your best just to make up the numbers IYSWIM?). But then again, giving it your all and having nothing to show for it at the end of the day is also a little daunting - I know that there will come a time soon when my dh will be expecting me to join the wage-earning population again and pay off our mortgage!Hmmm...lots to think about!!
Thanks again for your time.
