Mod Note: Note that the abbreviations do not use standard English abbreviations. The designer has defined Tr as "three stitches together" (= 3 stitches in the same base stitch), and Dec Tr as a "triple decrease, decrease using three stitches" and NOT as a treble stitch. The particular type of stitch (sc vs. dc etc) in the "tr" or "dec tr" depends on the row it is found in and the stitches around it (this is most often a sc, so DecTr=sc3tog, and Tr=3sc in a single st). Pattern is still workable, just be aware of these different definitions of the abbreviations. Video links are QR codes.
