I like most card makers we find some things 'challenging'!!! so for me it is boys cards esp. teenage boys but now Stampin' Up! are putting out more and more stamp sets that are so easy to use as boys/teens cards. Here I have used a variety of stamp sets to create the grungy look. The red piece behind the 'Happy Birthday' words was created by putting two label punch outs together - you can see it better on the close up photo below.
I find the best way to do these cards is to put a whole lot of elements together. I did make this with a teen in mind (happy birthday Sam for the 13th Aug!!) and he is interested in music, guitars and BMXing (hence the directional details) so just layer them up and BINGO you have a card. I have used acetate to give the appearance of more depth - it means that you can put details behind it like the coarse tape ribbon. Lots of hardware type things - eyelets, staples, clips etc - add to the masculine feel.
Thanks for visiting my blog - happy crafting :)
