Finally, I can do something not so simple. I found some acrylics at home. So, I painted the flowers with acrylic instead. Now, there's a rose garden on my nails. Loving it! Love these red, blue and yellow roses.
For the base color, I used The Saem Ardent Lady AJ07. Here, I painted 2 coats of the base color. Love this mint green.
Here, I haven't put on the top coat. I think if I have a matte top coat, it will look good too.
Painting roses are actually quite simple. Here is a video on how to do roses.
However, I want to make them last a little longer, so I had to use top coat. Giving this a glossy finish.
