The bottle I made is 5/8".
Choose a color of tissue paper:
Cut a piece 5/8 inch (or 1/2 inch) wide by 4 inches long.
Roll the strip around a round toothpick (cocktail stick).
Test the fit into the tubing piece and tear off some of the length if you need to so that it will fit inside the tube
I keep a small container with stiff plastic brush bristles clipped from a cleaning brush.
I use these to glue into the center of the bottle instead of a sewing pin or wire. Plastic bristles will not rust from the moisture in the glue.
Dot a little glue into the center of the tissue roll inside the bottle and insert the plastic bristle then thread one crimp tube onto the plastic bristle. Try not to use too much glue like I did. (select a relative size crimp bead to your bottle size)
Punch a circle from a 4-fold piece of your chosen color of tissue paper (again, the size depends on the inner opening of your bottle) and pierce a hole in the center. The tubing for my bottle here has an inner hole size of 1/8".
Thread this onto your plastic bristle and follow with another crimp bead with a dab of glue in between. Slide each down to the bottle trying to fit the first crimp bead into the center of the tissue paper roll. I used a little too much glue before the first crimp tube went on and could not see the center of my roll. My tissue roll was pushed down a little too far into the bottle.
Let all this dry a little and clip the bristle off to 1/16" above the top of the crimp bead.
I used this punch on thin cardstock to get a teardrop shape. You could also use a leafe shape acrylic fingernail rhinestone.
Glue the teardrop onto the tip of the bristle and let dry well.
Dot some dimensional paper glaze/glue onto the top of the teardrop and let dry.
This may work with clear fingernail polish. I have never tried this but please do experiment with what you have.
Use a gold marker to "paint" the shape and let dry well.
