Very pretty! We used to make these years ago with glass. The foil tape wr used was a little wider so when we folded it over it created a little frame around the coasters.
I personally wouldn't be too comfortable with a soldering iron touching near acrylic. I feel like no matter how fast you run it, it'll either melt or warp.
this looks like such a fun project. what flowers work best for drying. you started to talk about your thick book and paper, can you explain what paper you flatten the flowers with you never gave the link for the coasters and products you used. can plexglass work thank you,
why do skinny women always stick their chin out over their chest and slouch like that? It horrible posture. Be proud of being thin and tall, stand straight!!!!!
