There's no denying buying art for your walls can be expensive - even buying mass-produced pictures from the high street chains can add up and you could find yourself spending far more than you meant to, especially if you have a lot of wall space to cover.
However it doesn't have to be that way, as with a little imagination and creative thinking you could create a totally original look at a fraction of the cost.
Here are our favourite ways of sourcing free wall art ideas to build up a gallery that doesn't break the bank
Free picture ideas
Wallpaper samples
Yes, really! Wallpaper samples can make great pictures, and you can often get them for free! Samples usually come in A4 or similar size and you can frame them individually or create a collage from them.
We loved this design from Little Greene, pictured above with a picture frame bought for £1.50 in a charity shop.
Book illustrations
Book illustrations make great wall art, and browsing the books on offer in charity shops, vintage shops or car boot sales could unearth some real gems and pay dividends for your art collection. From vintage tourist guides, fashion annuals and gardening texts to beautifully-illustrated contemporary fiction, books can be a treasure trove of pictures whether you scan them or carefully cut out the originals.
The Concise British Flora in Colour (pictured above) was bought for a few pounds in a second-hand bookshop and contains around 80 beautiful botanical illustrations - which would create an impressive gallery wall!
Buy from Amazon.
And don't forget children's books, they often contain fabulous illustrations that could make a great set of pictures for a children's room or nursery.
Also keep an eye out for old magazines, sheet music and pamphlets - you never know when inspiration may strike!
Handkerchiefs and scarfs
When you're in the charity shops looking for books why not scour the accessory section for vintage handkerchiefs and scarfs for framing? Who knows you may score a bargain from Liberty at the fraction of original cost - it will probably last longer on you wall!
Post cards and birthday cards
Perhaps an obvious one but definitely worth mentioning! If you receive funny cards from friends, why not frame them? Or keep an eye out for quirky postcards on your travels. Whether you frame them individually or group a whole load together they can be memorable mementos of a trip or friendship as well as art.
Free downloadable images
There are many websites that offer free downloadable images, posters and pictures, often courtesy of institutions like the British Library, whose Flickr account has over one million images and illustrations for download. And if you love natural history prints, the Butterfly Trust has a great guide to hawk moths (pictured above), which you can download for free.
Old Book Illustrations offers a wide range of public domain, royalty-free images scanned from old books. For a wide selection of art, photos and posters head to Unsplash

Newspaper art
Old newspapers can be used to great affect on a wall. You can either use newspapers to wallpaper a whole wall, like this stunning bathroom wall above created by Shelby Mae Interiors, or to create unique pictures and collages. Older newspapers are a particular treasure trove, as you'll often find vintage adverts and cartoons within.
Honeycomb wall art
Turn wooden tiles into a statement piece, just like Diane has, by upcycling them with metallic spray paint and creating a bold pattern.
