This picture is from  Eva's DIY Blog Seidenfein   She also shows a nice way to use the butterflies.

These printable butterflies are from Katja's  DIY Blog shiftctrlart . You can finde the original pictures here . There are also various vintage nature prints. These painted butterflies are great for vintage projects.

These realistic butterflies are from the  DIY Blog Radiantik . The paper butterflies are colorful and large. If you print these, you should use stronger paper, so you can cut out the fine details. I can recommend paper with 120-140 g/m². This way the butterflies have a better structure and can be folded  without creasing.  Also with stronger paper  the paper butterflies containt their  shape/fold.


Some handdrawn vintage butterflies from an old german book about european butterflies.
