Men's cards are so easy... Either you keep it simple or you don't need to make any at all! I never understood the fuss about men's cards. All you need is some fun stamps, dies and papers. Done! As you're cutting out on embellishments, you could focus on a special technique such as Paper Patchwork or Iris Folding. There are so many amazing things you can do with papers.
For my Valentines' feature in Cardmaking & Papercraft (issue 165), I combined some cute stamps and sentiments. I worked on these in October last year before I went to Copics Classes with Faye and I like to think that my colouring wasn't too bad to start with!
Hope you found some inspiration!
