How do I affix Christmas candle lamps to narrow window sills?

What about Velcro? Once piece would stick to the window sill and the other to the bottom of your Xmas candles.

I would try bending tin strips (prob. 1/2" to 1/4" wide) into a shape that would hold down the base of the candlestick making the strips long enough to fit under the window. Making the window and the strips hold it in place. THEN I would somehow raise the cord up (tape, cup hooks, staples etc.) because it's probably the weight of the cord that is pulling the candlesticks off, or at least not helping any. You could put little pieces of greenery to hide the metal. My Papa always used copper strips for projects like this, but any metal that you could cut with scissors or tin snips and bend with pliers would work. He used to cut old coffee cans apart too. Or perhaps a strong wire, bent into the right shape. I would still put some type of adhesive under each one, even floral clay may help. But the main thing is raising up the cord. Good luck. Hope this Helps. Just Keep Trying and I know you'll figure out something. Just remember, YOU are smarter the the candlestick.

Poster putty may work. It looks like bubble gum and removes leaving no residue. You can put a wad underneath each candle. I bought it at Walmart but you can probably pick it up at a variety of stores.

I just thought of something else. How about push pins? Some to brace the back of the holder and some to hold up the cord (not into the cord though). Still something sticky on the bottom and Ivy, greenery, bows from ribbon etc. to hide the pins.

My suggestion is to use air-dry modeling clay to give a flat bottom to each candle. Onto your narrow window ledge, thumbtack or staple strips of white foam board wide enough to hold the candle holders. This expanding shelving can be decorated with some greenery and bows, or simply left if the ledge won’t be seen from outside. Merry 12 Days! ☺️

Very clever idea! Thank you so much!

Do your kids have any Silly Putty you could try?

Hey, I love the Velcro idea. You could just leave it one the sill for next year and not even worry about getting it off. OR, if you do want it off "Goo Gone" would get rid of the residue left by the bottom piece.... but like the one comment stated you may have to touch up the paint after, (if they are painted). Yes, my Papa was Very Clever. I miss him everyday!

I use Tacky Wax. I use it under my figurines so that they won't fall over. I use it behind a picture frame that seems to get crooked now and then. I bought mine at a hobby store and it is so sticky. Should be good for under your candles on the windowsill. Mine says (on the lid) Bard's Tacky Wax.

I'm going to look for this product at Michaels craft store. Thank you!
