Hi Mary Ann, after digging in deeper to this riddle myself and listening to others who gave this riddle a try, the riddle was missing a lot of information.  So I scrapped it.

The answers were:

Emma was crocheting a beanie with variegated yarn using single crochet stitches.

Mark was crocheting a scarf with worsted weight yarn using double crochet stitches.

Lily was crocheting fingerless gloves with sport weight yarn using single crochet stitches.

Sarah was crocheting a granny square with worsted weight yarn using single crochet stitches.

The person crocheting a baby blanket was using variegated yarn and double crochet stitches.

..... So much of that information was missing from the riddle part.  I thought it was a reliable sources.  I should have double checked.  BUT I did find some really good riddles that DO work and are quite fun.  I uploaded one to the Games chat if you would like to give it a try.  🤗

You are most welcome Jacqueline!  I'm glad I could provide something helpful for you!

I see a lot of overlap with most people.  I created this document by combining 3 different documents I found from Craft Yarn Council, the back of Crochet Magazine, and a crochet book I have.  They were each slightly different but I think I got the gest.  It's interesting what all is included and how someone might find that they don't necessarily need to know a certain skill based on what projects they focus more on.  🤷🏼‍♀️

Haha, totally get it.  This group of 3 squares is Month 3.  Wanted to wait for this month to begin before releasing the squares.  This week is Square #7!

It looks so great Darlene!!  The colors are so summery.  Great Job!!

Hi Joanne!  Ya, looking at the written instructions I don't see where that matches up on the diagram anywhere.  So, if I were you I would ignore the written instructions if you feel comfortable with that and just focus on the diagram.  It looks like the black squares are the ch 1, sk 1 spaces.  Then, after the ch 1, sk 1, you count the next tr st you make as the first of the next group.  It doesn't look to me like the is a filet style pattern where we are filling in boxes.  We are just working stitches and the ch 1, sk 1 holes form the pattern.  I hope this helps. It's a pretty pattern! 💖

This might have been a dud riddle that I found.  Sorry about the frustration.  I'll double check on the next riddle I plan on using to make sure it is a good one.
