I really hope you don't mind but again I have used the Fantastic Beautiful Day Stamp Set from Altenew, along with Kuretake Gansi Tambi Watercolours. I have the full 36 colour set, as I always regret it if I go for the smaller packs of anything and wish I had just gone for them all.
This card was so easy and enjoyable to do! I cut watercolour paper to fit a 5 x 5 card blank with a border, stamped around the edge in white using the rose outline stamp and heat embossed using white embossing powder ( I use WOW! bright white opaque regular. Then I took colour from the Gansi watercolouring using a water brush and added colour to the flowers. I wanted a sketched result so wasn't too careful where the paint went. I added shading by just using less water. Then I used the silver watercolour to add a pearlescent effect to the petals.
Finally I stamped the greeting from the set with Versafine onyx black ink to the centre of the square. i matted this onto black cardstock and fixed to my card blank using 3D foam pads. I added black pearls to the corners and there we have it!
