Today's post details my fondness for altering objects. They were fun experiences: both consuming the bottle contents, and subsequently altering it. 
disclaimer: These fun experiences did not occur on the same day.
Your first question might be where can you purchase a lamp kit for a bottle. I bought mine online, but you can try places like Home Depot or Lowes. I used a google search for online stores using the keywords: 'lamp kits for bottles'. They look like this:
To begin, empty a decorative bottle that you are drawn to. This Cuervo 1800 bottle actually spoke to me and told me it wanted to be altered into another object. Hence the lamp.
I seriously adore tequila folks.
I covered his shoulders with torn pieces of deep red mulberry paper and adhered using mod podge. His neck is covered with a strip of 7gypsies Catania paper.
The sides of the bottle were roughly traced onto the back of two pieces of Catania paper, then roughly torn around the pencil markings. Torn paper edges are much easier to adhere versus cut edges.
Crumple the torn paper for the bottle sides into two tight balls, then unfold and kinda smooth flat. Apply a Distress Antique Linen pad DTP (Direct to Paper: hold pad in hand and sweep across crumpled paper surface). The photo above shows before and after. Gotta love distressing!
Adhere inked sides to bottle with Mod Podge. Repeat above three steps for bottle back.
Tear a piece of Catania paper for the bottle front. Using a Tim Holtz Timeworks mask and working over a non-stick craft sheet, position mask on Catania paper.
Using an ink blending tool blend Distress Scattered Straw over and around the mask.
Continue to blend ink, changing ink to Distress Frayed Burlap. Wipe mask with a clean, dry, soft cloth and remove. Adhere to bottle front using Mod Podge.
Using this Tim technique, I smeared a non-stick craft sheet with Distress Shabby Shutters, Pine Needles and Peeled Paint, then misted well with water. Dropped a manila tag into the ink a few times and heat set after each dip. I love this technique - it's easily my favorite with these inks.
Distress tag edges with a paper distresser, then ink edges with Distress Brushed Corduroy.
Heat set the tag. Why? Distress inks don't dry right away, and for this step you'll need a dry tag.
Stamp one of Tim's stamps (Stampers Anonymous) using Distress Embossing Ink, then sprinkle clear embossing powder and heat set. (If you didn't heat set the tag earlier the embossing powder would stick to the entire tag - gah!). Ink over embossed image using Distress Peeled Paint and Distress Antique Linen, then wipe off with a soft, dry cloth, revealing the resist of the image.
At this point, I chose to cover the tag with blank newsprint and remove (melt away) the embossing powder using a craft iron. Why? I wanted to further stamp on the tag and wanted the embossed image to be in the background. You could omit melting away/removing the embossing powder; however, anything you stamp on the surface of the embossing powder would just wipe away where the ink hits the embossing powder (the embossing powder would act as a resist).
By melting/removing the embossing powder then stamping, you get the look below:
Using more of Tim's stamps (Stampers Anonymous) and Archival Ink in Jet Black, stamp images onto tag. I stamped a portion of the sentiment onto a piece of white cardstock that had Distress Worn Lipstick applied DTP (direct to paper) then distressed and curled with my fingers.
Added feet (Provo Craft discontinued these - I'm still upset...) using E-6000 cement, and an assortment of Tim's trinkets: Tim's Word Keys, Jumpring, Sprocket Gears held together with Tim's Long Fasteners; Game Spinners, Grungeboard wings painted with Aged Mahogany Crackle Paint, clock button (secured onto a smashed bottle cap), clock charm and hourglass charm were wrapped around the bottle neck using black fine burlap string.
Hope this post inspires you to alter something and have as much fun doing it as I did!
