6659 en <p>Hey Y'all!&nbsp;</p> <p>I'm Tish and I create hand-drawn and painted mandalas, mixed media encaustics, acrylic fluid paintings, as well as hand-printed marbled monotypes. I occasionally miss my jewelry-making days and have been known to pop out a small collection every now and then. I have a lot going on. LOL!</p> <p>I enjoy using my creativity as a meditative practice. It is how I cope with life. It is how I express my joy, sadness, frustration, and calm. Creative expression is also how I&nbsp;tune out and let the world fall away. Sometimes, I&nbsp;surprise myself.&nbsp;</p> <p>As you take a gander at my work, keep in mind your own joy, sadness, frustration, and calm. What resonates with those emotions? Which one speaks the loudest and makes you feel something? THAT is the one you want in your space! A conversation piece, for not just yourself, but for others as well.&nbsp;</p> <p>___________________</p> <p>I have been an artist all my life. After graduating college, I&nbsp;entered the non-profit art community as an Administrator, creating experiences for people looking to connect to their own creativity. My journey brought me into teaching my techniques to all ages and backgrounds, which I&nbsp;thoroughly enjoyed. I still teach art occasionally, hosting workshops around New Orleans. Currently, I&nbsp;am still doing administration in artistic spaces and until my work pays the bills, I&nbsp;shall remain in that role.&nbsp;</p> <p>Soooooo......who is gonna help me become a full time artist? ;o)</p> <p>Thank you for visiting my page. Your love and support mean the world to me. If you like what you see, share it with others.&nbsp;</p> <p><br></p> <p><strong>Return Policy</strong>:&nbsp;All sales are final.&nbsp;</p> <p>&nbsp; &nbsp;<em>* If a piece is damaged upon receipt, please document everything and contact me. I&nbsp;insure all of my work for shipping. Since most all of my work is original, one-of-a-kind pieces, the possibility of reproducing a replicate is very low.&nbsp;</em></p> <hr> <p><strong>Processing Timeframe</strong>:&nbsp;Please give me 5 - 7 business days to get your work together for shipping. You should receive your art 10 - 15 days after purchase.&nbsp;</p> <p>&nbsp; &nbsp; <em>* Currently, I do not ship internationally.</em>&nbsp;</p> <hr> <p><strong>Disclaimers</strong>:&nbsp;All work listed on my site is 100% my work. I do not use images from other artists.&nbsp;</p> <p>&nbsp; &nbsp; <em>* Regarding encaustic work:&nbsp;Wax should not be exposed to high heat or areas of the house that receive a lot of light. If you need a consult about this, just contact me and together, we can find a spot in your home that is perfect.&nbsp;</em></p> <p><em>&nbsp; &nbsp; * All of my work is sent to you ready to hang, with the exception of my marbled monotypes. They will need to be framed.&nbsp;</em></p> <hr> <p><br></p> {"tmenu_style":"V","default_colors":"N","link_color":"#007d89","label_color":"#00a0af","icon_color":"#00a0af","main_btn_color":"#6dd1d6","branded_text_color":"#00a0af","vbp_1_url":"","vbp_2_url":"","vbp_3_url":"","vba_1_url":"","vba_2_url":"","vba_3_url":""} TD Studio 243 Delaronde Street New Orleans A TD Studio 243 Delaronde Street New Orleans US 70114 tish.douzart@gmail.com +15047232056 none Y 1652395021 0 3 acct_179NXrFhj4LnmikY www.facebook.com/tishdoesart www.instagram.com/tish_douzart A N 0 0 0 0 0 S Professional Plan tdstudio 6659_0
