if you're willing to invest $20, I have a recommendation. I justacquired a copy of "Knitting from the Top" by Barbara Walker. I did alot of searching for top-down, in-the-round design resources, and thisis by far the most complete one I've come across. It describes notonly raglan designs, but also yoke shoulders, set-in sleeves, saddlesleeves, and more. It is not a pattern book; there is not a singleset of stitch-by-stitch instructions. Rather, she describes themethods of construction in detail, and gives you the tools you need tocalculate your own stitch counts to fit your measurements. You alsohave to come up with your own color and/or texture patterns, assumingyou want anything other than plain one-color stockinette. However, ifyou have a bottom-up raglan pattern that you really like, with thisbook you will likely be able to adapt it to be top-down.
It can be a little hard to find. I ended up buying it from
knitpicks.com, which has it in stock at a discounted price of $18. If
you add something else to your order to get up to $30, shipping is
free. (It's pretty easy to find something to buy at KnitPicks.)
If you google "top down raglan", you'll likely find some other
Hope that helps!
Depending on how adaptable you want the pattern, there's
walks you through a formula to design your own.
Also, I've made a couple of children's top-down raglans from an Ann
Norling pattern that's very versatile: #53: Kid's Basic: Top-down
Raglan $6.00 which you can see at
I've got an ancient copy of Leisure Arts "Complete Book of Raglan Sweaters"
that I love...It gives a slew of sizes (6 mo. to size 50) in four different
weight yarns and in about six different patterns (striped, fair isle, etc.).
