For a while there has been a growing trend in using party printables to decorate parties.  There is an abundance of choice, especially on Etsy, including the option of having your printables personalised.  I love the idea of party printables as it means you can have a fantastic design for a party but without a hefty price tag.  The designer will email your printables to you which means you do not have to wait on Royal Mail to deliver.  This is also great for the less organised amongst us as the designer is often able to email you the files within 24 hours, if you are buying a standard design that does not require personalisation. But the biggest bonus of all is that you can order your printables from a designer anywhere in the world and not have to worry about postage charges, as your party printables are delivered for free, to your inbox.

Whilst this all may seem really easy I would strongly advise you to purchase good quality paper to do the great designs justice when you print them. A 120gsm weight paper is good for paper bunting or cupcake toppers but 160gsm is even stronger and won’t curl so easily.  For printable invitations I would strongly advise a 220gsm or heavier weight cardstock, but this would depend on your home printer as many dislike anything heavier than a 220gsm weight card/paper.  To complete your bunting or banners you could use bakers twine or thin ribbon and double sided sticky tape is always handy as I have found PVA glue can make ink run if you are using a deskjet printer.
