Keep fancy invitation cards and matching envelopes ready with you at all times. Should you decide to host a party at the last moment, you can always utilize stationery that is already in stock to ease the process.
While many people resort to online invitations these days in order to save on time and money, nothing beats the warmth of a personalised handmade or paper invite.
While invitations and envelopes may not be direct party supplies, they are essential accessories that are important all the same.
A bunch of decorations
If you have children or plan get-togethers often, storing a bunch of party decorations like balloons, streamers, paper based designs, animal stickers, shapes, colourful hanging lanterns and more it will help you. Not only will you have to spend lesser time running around for decorations at the last moment, you will be able to plan a party in a matter of days.
What makes this idea even more worthwhile is that you can use the store bought party decorations to spring surprises on your spouse too on special days. For this you may need a slightly different list of decorations like candles, ribbon and confetti, etc.
Make it different
Everyone focuses on cleaning the house, prepping it up for guests and dishing out a great meal at dinner parties. But you can make things different too. You can experiment with name cards and actually create a menu and put it up on the table. Create a unique set-up to people truly end up marvelling at how well you have planned the evening.
