Can you see the underlying pattern that was stamped all over the card in white ink first? That is the velveteen technique. Here is a full shot of my card:
supplies: blue card, white cardstock, Hero Arts CG335 Dot Flower Pattern, Colorbox Frost White Ink, CG278 Four Fun Flowers, sentiments from CL491 Made with Love, CL341 Thank You Sayings, CL497 Find Joy, Hero Arts mid-tone inks pool, butter bar, and green hills
Briefly, to get this effect you stamp a background stamp in white ink on white cardstock, then overstamp the sentiments and flowers using colored inks. You get the best results when your stamps are solid rubber, so that the underlying pattern can show through......I was surprised to see it come through on the biggest sentiment also!
