I just tried the glue stick using card stock paper hexies. It worked great. My glue stick is the Sewline too. But isn't that a Sue Daley product? I have lots of Elmer's washable glue sticks. I am going to heat the glue from one and pour it in an empty pen refill. Let it set and..... who knows it may work and if it doesn't I'm out a little time and spent about a dime. The refills are not that easy to find in my area and ordering the shipping is more then the refills.
