Materials and Techniques on Monday / Working with Yarn Cakes + Raglan

Dear users, dear authors,
you know how it goes: Mondays are all about materials and techniques. I suggest that this week we focus on working with yarn cakes and raglan sleeves (from the top and from the bottom), since there will be promotional threads on these topics. That fits together quite well.
What comes to mind when you think of these two topics?
Of course, you’re also welcome to discuss any other material and technique topics.
Have fun.
