First 2 cards I used a more straight line brush stroke, also dry brush look, but even though I aligned them carefully with the grid on my stamp buddy, it kept looking skewed to me and the distance between the brush I eyeballed and it was all wrong ;-)
So I switched stamp and used a scribbly one that looks more like a wet brush, if that makes sense to you.
For all cards I started in the middle with yellow so that was positioned properly and then the outer ones (red and blue) and orange en green to center them, I thought that worked well.
I used the back panel from one of the other cards as paper has two sides and made it a raised panel instead of my intended one layer.
For my stamping I used Ranger dye inks ( classic
cherry, cheese puff, lemon twist, electric lime and Caribbean coast)
I then used a butterfly die from Joy! crafts (6003/0023) and diecut it from black cardstock with doublesided adhesive on the back, so it becomes a sticker (I used Elizabeth crats but Ken Oliver stick it would work great as well)
Did the same for the sentiment die from Crafter's companion Die'sire.
Stuck the panel on the cardbase with foamtape..
