3956 A & D by The Tall’n

In this puzzle, the grid (without any horizontal bars) was presented with an irregular numbering scheme. Some answers, we were told, had to be entered in an unspecified thematic way. The entry method had to be deduced from a theme word linked to some of the thematic clues. This made for an interesting and enjoyable challenge.

Thematic answers of one type were HITCH, SHAPED, BASEBALL, DUST, DOVE, KOH-I-NOOR, CULLINAN, BEETLE (all of which can be linked with DIAMOND to create a longer word or phrase), SPARKLER and RIVIERE (both of which can be associated with diamonds). Therefore, D answers had to be entered in the grid using adjacent cells, forming a diamond shape as the answers were spelled out.

The other ten thematic answers were PAPER, LEATHER, IRON, WOOL, STEEL, LINEN, LACE, CHINA, RUBY, and GOLD, which are all gifts associated with wedding anniversaries. These had to be numbered with the clue number appropriate to that anniversary, so that RUBY was numbered 40, etc. This completed a sequence of  numbers from 1 to 50 in the grid. Finally, (the puzzle being timed to coincide with the 60th wedding anniversary of the Queen and Prince Philip) QUEEN’S WEDDING ANNIVERSARY and SIXTIETH had to be completed - these appeared as two D answers, and had to be highlighted.
