Every quilt is different for me. Sometimes it's choosing the fabrics, the thrill of knowing I found the perfect fabrics. Often, it's finishing the final block and knowing that the assembly of the quilt comes next. If I know what I want to quilt, the quilting is my favorite part. There's always a little thrill when I'v finished the binding and it's complete.
By far, my favorite part, though, is seeing a quilt i've made in use. When I go to my sister's home and see my neice's quilt on her bed... or see that my sister cuddles in her quilt in front of the tv every night..Or seeing a baby quilt that's clearly been laundered plenty and is being used... That's the best part!
