I have arthritis and found this item to help me with glue basting. Works terrifically!!!
Here is a useful item. I am not affiliated with Lee Valley. My DH was ordering from their catalog so when I saw this I knew I could put it to good use in glue basting. This is very inexpensive and one of hte 3 different sizes of tips will work for you... I am sure.

I completely agree with EasyPeezy on post #2 about starting out with a small project or scraps. It is easy and you will get the hang of it. Try not to be afraid of it since it is washable and will all come out. Even on your iron.
PS: sorry Jan, I almost forgot to answer your question. I have used all of the photos you have shown. Not sure which I like the best. They all work and if you get tooo much, you can always swipe it off with your finger.
