Two updates to the earlier post about embroidery: First, your pattern doesn't have to be complicated to be darling. Look online at vintage linens for inspiration. You can also simplify by choosing a simple color palate or using white thread on colored cloth. White thread on white cloth is also fun and allows for a few more "goofs" in the stitching.
Next, if you are shopping for supplies look online. Joann.com is currently having a big sale. Plus, you get 40% off the most expensive item you purchase with a coupon code. It's really hard to find embroidery supplies in San Francisco, so shopping online for your floss and loops makes sense.
