I have been making beaded pens for a couple of years now. I personalize them and give them as a reward to my outstanding students. I also make a box to go with the pen. I have made the boxes with acetate but it is time consuming and hard to glue. I've also used cardstock, but the pen can't be seen. So I combined the two and made a with a window using acetate to cover the opening. I used a CM square punch to cut it. I liked the result. The last week I made 28 personalized pens and boxes! It was lots of work but my wonderful students deserved them! it was so rewarding to hand them out as gifts!
