You gotta be fast with foam and CA glue. Pinching the piece together hard before it dries. I use mostly the fingernail glue. $1.50-2.50 and the double deal $1.00 at DollarTree. Some like Krazyglue have brushes. Gotta keep the holes open with bodkin
Use foam for a lotta stuff...
Awhile back I did a bunch of stacked craft foam popper bodies. I glued them with contact cement. Messy but solid. And you gotta get it right the first time. No do overs. I cut most of the plugs with improvised cutters like yours, then bought a punch set at Tandy leather. I get some good effect gluing a large sequin on the front of the cylindrical poppers, it gives them a nice dished face in the color of your choice.
Or a Cricket Frog, both of which are far more numerous in my parts than Pickerel or Leopards. I like those little froggy ideas, good thing to have in the 5 wt box for bluegill/bass excursions. Slightly more noticeable than a spider, yet tempting in profile and easier to cast for bass.
If it's dead calm, I do well on small spiders for picky bass. Any wind or ripple, it's like they don't even notice it. Gonna give the mini-frogs a shot this year...if I can do it without gluing the f-ing thing to my finger. I'm bad with CA glue like that.
