Back then we decided on a big joint project: a bedspread of sparkly yellow granny squares with a sparkly white flower in each center. I'm thinking that the yarn was the legendary but discontinued Dazzleaire.
Nowadays we live in different states so we haven't gone yarn-buying together for a long time, but Mom sends me some of her crochet and she's excited for me about mine. (See photo of me mum's crochet.) A few years ago we both were really into crocheting with wire and beads. Then Mom went whole-hog into thread crochet, the finer the thread the better! Also, needle-felting.
If I still had one of the sparkly granny squares I'd post a photo.
