Jessie has a shoppe called Cake Spy. I've been happily reading her blog for some time now, and am quite pleased to write about her on my blog. Her drawing style is RIGHT up my ally! She has her own adorable drawing style, and humorous adventures her little "cake spy" takes.
I have been making stuff since before I can even remember! My mom has a picture of me in my high chair with pigtails, concentrating intensely and coloring happy faces.
That having been said, I am rather new to the crafting culture, and so far have only been doing framed pieces. I am looking to add cupcake plushies and figurines to my offerings soon.
I try to get inspiration from everyday life, in a flaneur-like fashion: bakery cases, cool buildings and architecture, and magazines and books. I also love a lot of "blogs" out there, from design-y ones like Oh Joy or Decor8 to foodie ones like Cupcakes Take the Cake, Whipped, Bake and Destroy and the Urban Housewife. In terms of art, I love great line drawings--some of my favorite artists are Saul Steinberg, James Thurber and William Steig; for painters, I adore Wayne Thiebaud (the cake guy!) and Jean Miro.
Some challenges I've found have been cost of goods--since I sell framed pieces, the costs can really add up so I have to be smart about that. Also, it might be a little bit outside of what you asked, but taxes!! It's a whole lot more to keep track of than if you had a day job and had your employer do it all for you. I have to mentally take 20% off of each sale for the taxman!
She's a very talented gal, so go check out her etsy, and then head over to Jessie's blog to read about the cake she spies. :)
