A few of them. I have more ideas than finished things, but I'm getting there:)
Numbers for candles in the Advent candlestick. I drew the numbers on paper and then bended iron thread following the lines on paper.
Modern paper decorations. Instructions can be found here (by Design*Sponge).
My iron heart. Very easy made decorations. I only used 7 pearls on each side, but take 8 pearls instead, I think you'll get a better heart shape if you do.
An angel. Start from the bottom when making this one.
I'm in love with iron thread and tree pearls. So last Monday before noon I made new cuffs for my electric candlestick. I'm using red, purple and gold in my decorations this year.
A simple decoration and a good storage idea is to put colorfull or plain white candles (depending on what you prefer) in a glass vase. I think putting white candles in a tin jar would be excellent as well.
Hopefully you can get some inspiration for your own decorating from this post.
Have a good day, second Sunday of Advent.
