thanks for the hint. Let me mention alternatives :-)

For those who prefer QGIS, I suggest the QuickWKT plugin where you can paste 
If you select a feature (existing, or just created), copy and paste it in a 
text application, you will get the WKT.

Otherwise (limited to WKT), you may also create a simple .csv file

1,"your WKT"
2,"your WKT"

and open it with QGIS. (the WKT colum name is critical so that the column is 
recognized as a geometry)
