There's a very cool challenge "POP up" challenge at The Daily Marker blog along with inspirational videos on how to add lines to your card making and incorporate coloring too. Click here for the direct link to the challenge post. I'd also like to enter the masking challenge at Happy Little Stampers (click here for the challenge): my masking is really basic -I just masked off the top half of my card but I hope this qualifies anyway!
I've used line stamps from PTI and a STAMPlorations sentiment stamp in my card. I colored the spaces between the lines with my Copics -no shading this time. I decided to use a monochromatic color palette. I really like the graphic look of this and am grateful for these inspiring challenges! I had fun!
