A few days ago, I created this cork wall art piece to go over my wine rack, and I'm not going to lie, it was quite time-consuming, but quite easy as well. I am very happy with how it turned out.
I bought an unfinished wooden tray at Michael's, (it cost about $2.50) and stained it with a dark walnut stain (which I already had, but you can get them at Home Depot or Lowe's for less than $5).
To cut the cork pieces to the correct height, I used the height of the tray. It doesn't have to be perfect, but this will get you close enough to the proper measurement.
I used the wine stained parts of the corks to create the vine grape, and the word "VIN," which is "wine", in French ~ but I am sure you already knew that :) Before gluing the pieces, I arranged them the way I wanted them to appear. Make sure it is centered the way you want on the tray. Once you are happy with the way it looks, glue each piece with all-purpose glue. I do not recommend using hot glue, since that will not allow to correct mistakes along the way. With all-purpose glue, you will be able to adjust as needed before it dries.
Fill in all the areas around the wine stained pieces with natural colored cork pieces. It will be like putting a puzzle together. Start with the round pieces, then fill in the "blanks" with smaller, made-to-fit pieces.
Here is a close-up:
If you'd like to darken the wine color on your design, you can use actual red wine and apply it with a small paint brush to the areas you wish to darken (another perfectly good excuse to crack open a bottle!). Be careful not to go over any part you do not want darken, because the wine will stain it right away. Happy crafting!
