if you have a naked wall and you want to have a very special decoration, why not make a family-artpiece?
i suggest two possibilities:
1. bying a big canvas
2. bying for example four small canvases, if you are a family of four
choose than the colours that would compliment the area you want the piece hanging.
everybody in the family, no matter what age, gets to decorate one small canvas or you decorate the big canvas all together.
try to use different techniques, like using a sponge as a stamp, covering areas with tinfoil, colour and then taking the tinfoil of, using bits of old newspaper or pictures from magazines...
the options are basically unlimited. you might want to practice one time on a cardboard, to see how it goes.
if you have very small children, just let them paint and print with their hands. use paint that is safe to get in the mouth...
in the end it`s important to fixate.
if you choose the small canvases, you can put them together in a square or in a row on the wall.
you can have a distance in between or put them close together.
this is really a fun family project and might inspire the whole family. it will become a really nice memory and gives everybody a feeling of being a part of the family.
i recommend especially making this artwork for patchwork-families, such as mine:)
and: you get a really beautiful decoration on your wall, that nobody else has!
if you want to have a bigger artwork or one of you is extra gifted in arts, you can double the amount of canvases and this one person can decorate these and put them in between. or you can glue on a matching fabric, wallpaper or anything really. there are so many possibilities!
have really good fun with this!
