Creating a stamp
Start with a rectangle.
Add a circle, align the circle’s center roughly on the top of the rectangle…
…convert the circle to a path (SHIFT & CTRL & C) and duplicate it three times.
After duplicating and moving one part upwards, add some decor to the roof (e.g. some lines) and group this side of the roof.
Duplicate the group and mirror it to create the complete roof.
Select the top row and ungroup (Object/ Ungroup or SHIFT CTRL & G).
Combine the row of circles with the Path/ Union command, followed by duplicating the object. Move it to the bottom and cut it from the base shape it with the Path/ Difference command.
With the basic elements in place, it’s time for some decorations.
Two more rectangles make up the boards on the front, a square is turned into a window and combined with another rectangle and a circle makes the door.
The reason for ungrouping and combining the circles first lies in the restriction in Inkscape to only do a Union, Difference, Intersection, Exclusion or Division between two objects. Tools like CorelDraw can do these with a group or even just several selected objects. Try around a little see how your vector application handles these very handy commands.
