Sometimes people are a little concerned about joining after the class has started  Although it's nice if you can start at the first week it's not always possible and there are many people who due to some other commitment, (a holiday for example) end up joining part of the way through the class at a reduced rate..  This actually works quite well. You may be quite keen to do the class now whereas in a few months time your circumstances may have changed.  It may also be that the class you are interested in is full and you have to go on a waiting list anyway but get in touch and it maybe possible to sort something out. You never know and your creative journey may end up starting sooner than you think!
