Great, sugarcookiebunny! Here's a basic pattern to get you started:

Materials: - Worsted weight yarn (approx. 1200-1500 yards) - Size 7 (4.5mm) circular knitting needles - Stitch markers - Tapestry needle

Gauge: - 18 stitches and 26 rows = 4 inches in Stockinette stitch

Instructions:

Cast On: - Using long-tail cast-on, cast on 108 stitches.

Body: - Work in stockinette stitch until the length of the sweater measures approximately 16 inches from the cast on edge. - At this point, insert stitch markers to divide the front, back, and sleeves. For an XXL, divide as follows: 28 stitches for each sleeve, and 52 stitches for the front and back each. - Continue knitting in stockinette stitch on the front and back sections, and switch to double pointed needles or magic loop method to knit the sleeves.

Sleeves: - Knit 28 stitches in stockinette stitch for each sleeve. - After completing 2 inches of the sleeves, increase 1 stitch at the beginning and end of every other row until you have a total of 44 stitches for each sleeve. - Continue knitting in stockinette stitch until the sleeves reach your desired length.

Neckline: - After reaching your desired sleeve length, join the front and back sections with Kitchener stitch or a 3-needle bind-off. - Pick up stitches around the neckline with the circular needles and work in rounds, decreasing 2 stitches every other round at the neckline, until the neckline is the right size for you.

Finishing: - Weave in all ends and block to the desired measurements.

Hope it helps. Have fun knitting your sweater!
