I have tried to enter the answers I have.
I have entered 1a as suggested. I can use the letters 1,2,4,6,8 for Down clues 3 to 7. The I get into trouble. The last letter of 1a can be used to enter 8d.
But then the symmetry is lost.
Also where does the 10 letter answer to Close-fitting go? (Row number).I cannot see any row that it would fit in.
Same thing with the column number for answer to Bugs (8 letter).
My grid entries for others are most likely wrong.
(I have 1d in Col. 1 and 2d in Col.2)
Help!
