I think one reason why more people don't use Lekala is that the designs are not well presented. There are like 4 or 5 different illustration styles. Many of them do not show the design details. I appreciate that Bootstrap has used the line drawings instead.

While there are some nice patterns, others look like they are stuck in the late 70's/early 80's disco era.

Also, the site is rather disorganized (seriously, tops both woven and knit can be found either under Blouses, Shirts, or Tops - you have to look all three places).
