168 en <p> <span class="display-block"></span></p> <p>I am a Colorado native and absolutely love this beautiful state. I initially started my etsy shop doing lots of sewing of baby items. After my husband passed away, there was a need to be supporting myself with my Etsy shop. I have fallen in love with glass etching. In November of 2012, I saw some personalized baking pans and had a thought that I could do that. That Christmas season I sold a decent amount to family and friends locally. From there my business has blossomed into so much more. I do professional sand blasting and love it so much. The Christmas ornaments and coffee cups are new to my site this year. I have loved being able to find my glassware and branch out.</p> <p><span class="display-block"></span></p> <p></p> <p><strong>Processing time:</strong> <br></p> <p>The time I need to prepare an order for shipping varies.
