Very useful. I wish I had seen this the first time I made some whoopies.
"The real man smiles in trouble, gathers strength from distress, and grows brave by reflection."
I think that's a great tut, us. If you had a wire fid it would only take you a fraction of the time it takes you with the pen and tape. What I and some others use is a piece of 26-28 gauge wire doubled over, this will make it much faster. I do like that you used what you had on hand, though.
Welcome to HF's btw!
