Will this make a big mess in the kitchen?

I worry about sticky counters and drips. I have done this many times and it usually stays tidy if you keep a tray and paper under your workspace. Wipe spills quickly with a damp cloth. The wet mix rinses off countertops with warm soapy water. Have children work on the tray and keep a bowl of soapy water for quick hand washes. A few sticky spots are normal, but they clean up fast.

Is this safe for young children and what age is best?

This process has a short stove step, so an adult must handle that part. Kids as young as three can help with mixing in a bowl, placing decorations, and sanding edges under supervision. Older kids can pour and place details with a steady hand. Keep hot tools and the pan handled by an adult. Use poking tools only with supervision to avoid burns.

What if I do not have glycerin or want to swap an ingredient?

Glycerin is optional. The mix will still set without it but may feel a touch stiffer. If you skip glycerin, make slightly thinner pieces so they bend less. Do not replace vinegar; it helps the sheet set. The core recipe works with tapioca starch or cornstarch as listed.

My suncatcher looks cloudy or cracked. Did I do something wrong?

Cloudiness often means the mix did not cook enough or had small lumps. Warm it gently and stir until glossy next time. Cracking usually comes from thick pieces or fast drying. Try thinner layers or add the optional glycerin to improve flexibility. Small flaws are normal and you can sand or trim them away.

How long do these last and where do I keep them?

They last quite a while hanging in a window away from direct, strong heat. Store flat between sheets of paper if you take them down. They can yellow a little over months if exposed to harsh sun, so rotate or move them indoors for longer life.
