So if you have been searching for a beautiful blanket using bulky yarn with zero color changes, this is the perfect afghan blanket for you!
Skill level is confident beginner which most beginner crocheters tend to be now a days! Using two colors of medium weight 4 yarn and a 9 mm crochet hook for this great project. This is my favorite crochet chunky yarn blanket but made with 2 strands of yarn. You can use worsted weight or aran weight yarn, it’s your choice. The yarn weight is slightly different for aran weight yarn and worsted weight yarn but will not be an issue for this free crochet pattern.
My favorite type of yarn for this project is acrylic medium weight yarn is Lion Brand Pound of Love or Yarnspirations Caron One Pound Yarn for project such as blankets and clothing. It’s soft yarn, comes in lots of different colors and is great for this crochet projects. Yarn colors used in my sample is purple and white. You can use one single color of yarn but you need to use two skeins at a time to get the right thickness for this afghan.

For the sample afghan, I used 5 skeins of yarn and here’s exactly what was used for my sample: 3 Skeins of Yarnspirations Caron One Pound Yarn (White) and 2 skeins of Lion Brand Pound of Love (Thistle Chardon) which is purple or any two colors of yarn. The color scheme is up to you but any time you use white colors with a darker color, the contrast is the best thing.

Free Crochet Afghan Pattern One Piece – Tips and Tricks
Color Play: Experiment with different color combinations for a personalized touch. Whether you prefer bold and bright or soft and subtle, the bobble stitches will showcase your chosen colors beautifully.
Blocking: You don’t need to block this blanket. Blocking is for granny squares, save your time and energy and skip this step.
Two Strands: Keep on eye on your yarn and make sure you watch it closely to ensure you are still pulling up both colors. It’s easy for one color to fall off your hook. Rip out and redo if needed.
ESC Stitch: Tighten your tension yarn up after each stitch.

Bobble Stitch: Make sure you pull up before you pull final stitch to close the bobble. If you gently pull the hook with all the loops on it upwards AND face crochet hook teeth down, then pull up and through it works best.
Stitch Markers: Use stitch markers to keep track of your bobble stitches, only if this helps you. I personally never use stitch markers but use what works for you and your skill level.
