Thanks for taking Understanding Symbol Crochet! I hope you enjoyed the class and left with the confidence to tackle any charted crochet pattern.
The chart on page 3 of the handout is for my Cascade of Color Scarf; you can find both text and charted instructions in the pattern.
You can find Duplet (Russian/Ukrainian magazine) sold here.
Take a look at my free Creativebug how-to class on How to Read a Crochet Pattern (both text and chart). You’ll find that all my books have both charted and text instructions to make it easier to follow, no matter which method you prefer.
This page includes a lot of good resources for better understanding symbol crochet. Scroll on down the page to “Beyond the Basics”.
