I'm currently working on my Father's day cards, i've already made 4, and now need to do the remaining 3. I'm actually really enjoying them which is unusual because i normally find men's cards really tricky. I'm finding Claire Curds range which includes the big paper pack and male stamps a real help and the Forever Friends decoupage range simply because there are so many you can use for males. The best tip i can offer when doing male cards though is to get on the blogs, particularly Do Crafts and check out what other people are doing - you can get excellent inspiration from other crafters work.
Over the course of this week i've got to try and get my brother's birthday cards done. All my family have asked me to come up with cards from each of them for him, so that's going to be a challenge, though i have already picked out some things i can use like the lap-top man from Paper Nation and Racing car images from Kanban. So fingers crossed they will turn out okay.
I'll keep you posted on how they turn out!
