Reddit mentions of 2 5/8" x 1" Silver Foil Address Labels for Laser Printers - 300 Labels

Or, if you got money to burn and are aiming for ~elegance~, get an embosser. I get all of mine from Wiltshire Graphic Press and have been pleased as punch with them. I have 4 plates and I still want more... I think I have a problem :P

Pricey, yes, but they're really awesome, willing to work with you to make sure you get exactly what you want in whatever size, shape, and/or font you want it, and you will not be disappointed.

My sizing recommendation:

• get the regular (short) version if you plan to emboss:
  
• only the back flap for address labels
  
• top/bottom/side/corner edge of standard sheets of paper (custom stationery, trés chic!)
  
• only stickers/labels exclusively (which is what we did)
  
• get the extra long-reach embosser only if you are planning on embossing address labels onto envelopes directly in the standard upper-left area on the front (for Americans, not sure where other countries put their return addresses)
  
  The regular embosser can sort of reach into normal envelopes to emboss the paper directly, but the result will be crooked or the paper will crinkle from being jammed into the embosser's throat no matter how careful you are.
  
  Other thoughts:
  
  
• If using stickers/labels, make VERY SURE that your embosser plate will fit on whatever sticker/label you buy!!!
  
• You will not be able to emboss cardstock
  
• Don't use too much or too little force. It'll take you a few tries to get the optimal pressure for an uniformly-embossed impression.
  
  Our rave for WGP: I originally bought a desktop embosser from WGP with just our last name and address on it since hubby's mom has had an embosser for years and I really like it. I didn't mind using his last name early since it'd be my last name eventually and I didn't really want to spend $35 to get a "Mr. and Ms." just to use it for the duration of our engagement only to chuck it out and spend another $35 for a "Mr. and Mrs." version. Ain't nobody got money for that. The WGP embosser still performs beautifully even after what's got to be thousands of impressions, still crisp and clear and very easily readable.
  
  Later during the wedding planning phase, I/we had a brilliant idea. Hubby and I are a bunch of nerds and wanted an insignia monogram, but the normal traditional letter-only monograms are so boring and same-y. We paid for artwork featuring a calligraphic monogram incorporating elements from both of us and plastered it everywhere in the wedding:
  
  
• the wedsite
  
• silver address labels for envelopes
  
• round silver stickers for the back of envelopes (STDs, invites, thank-you cards) (these but in silver)
  
• treat bag labels (we bought a circle die-punch like for scrapbooks, cut out cardstock, monogram-embossed round silver sticker on the back and guest's name on the front)
  
• cupcake toppers (same as above, but with a extra-long toothpick stuck in the cardstock halves)
  
• our venue offered light discs to shine on the dance floor - $300 savings there since we already had the artwork done
  
  You name it, if it could fit a 2" round silver sticker, I put a sticker on it. I blame my 8 year old Lisa Frank inner self. :> And you know what? It was worth it, because every single person who came to the wedding (and even some of the vendors!) complimented us on how elegant and personalized the whole thing was.
