keep the colour scheme to no more than 3 colours, if you find yourself wanting more colour use varying shades of one of the colours.
you can always make the cake yourself, i don't care if you use packet mix or even buy the sponge from woolies, having the creative control to match the colour and style to your event is going to make the cake shine rather than stick out like a sore thumb. you don't have to go overboard with the decoration, remember simple is beautiful.
when it comes to baking the desserts, create a time plan - make sure you start as far in advance as you can, and remember that when you have one dessert in the oven you can prepare the next one so that it's ready to simply swap out.
use fresh flowers or foliage if possible, it will add life to your styling and help break up any inanimate props.
balloons are always appropriate, no matter the age of the guest of honour or style of event.
while i'm usually an advocate for symmetry on dessert tables, try mixed serving ware to create a relaxed feel and make things even more visually interesting - just keep things within your chosen colour scheme or use neutral colours like black white and grey.
think outside the box - desserts can be arranged on many different items to create interest. don't limit yourself to cake stands, think of acrylic laptop risers, trinket trays, chopping boards, boxes or other styling objects which can be used to add varying heights.
to create an elegant feel try to avoid disposable plates and cups, instead try simple glassware and white dinnerware - you can find very stylish and affordable options from the likes of kmart.
cloth napkins are an easy way to elevate your table style and make things appear more fancy than they may be.
try to not to use too many plates, dishes, serving plates on your table - the last thing you want to have to do is spend the rest of your night washing up.
have a plan for how your event will run - eg. drinks on arrival, followed by a sit down dinner, the cutting of the cake and dessert table grazing.
there are so many things you can diy - from invitations to gift bags and everything in between, don't be afraid to give things a go and get creative, you'll surprise yourself just how crafty you really are.
enlist help - you don't have to do everything yourself, don't be afraid to ask a friend to help out even with menial tasks remember that a job shared is a job halved and as long as you have company you might even enjoy it.
if you have an event in mind, but don't know where to start, i'd be more than happy to point you in the right direction and offer any helpful suggestions i can. if you're in the rockhampton area, i'm more than happy to have a chat with you regarding your event, share my local contacts or even my recipes.
