Some doodles and early tiling technical exercises to figure out the software behavior, this culminates in later refinements of this watermelon vine pattern as well as the tutorial I have published on tiling / Surface Design in Inkscape which if I recall features some notes on GIMP and Krita as well. Generally, any of these tiles can be previewed in GIMP, checking for errors and continuity, using the Offset tool dialogue at Layers > Transform > Offset. This works on one flattened layer at a time.
