I've done a quick test with one of my latest purchases; Isadora - Latte queen. It was a spontaneous purchase since it was on sale. However I liked it, I only have colored crackles before and this is more neutral allowing more colored base colors.
I've been wearing some pinks this week so I thought it was a good idea to test it of with pink. The pink base is from Paris Memories and as you already know, the nudeish crackle color is Isadora - Latte queen. I've already got some ideas for nail arts with this which I hope will work out. :)
