+  <p>
+   Valentina is a cross-platform patternmaking program which allows designers 
+   to create and model patterns of clothing. This software allows pattern 
+   creation, using either standard sizing tables or an individual’s set of 
+   measurements. It blends new technologies with traditional methods to create 
+   a unique pattern making tool.
