- Yarn Berry Fun Yarns are dyed naturally, without the use of toxic chemicals. The colors are coaxed out of the beautiful plants and flowers (or even coffee that Grandpa drinks!) that fill the fields of Firefly Berries. We do purchase a small amount (less than 10%) of our dyestuff or natural extracts from trusted U.S. dyestuff companies, as there are a few colors that are we are unable to grow in Minnesota. Dyeing yarn naturally is different than using acid dyes in many ways, but the most striking to the dyer is that naturally dyed yarns are highly sensitive to the pH of the water used both in the dyeing and washing process. A slight change in the pH of the water can yield an entirely different color. Because of this, we recommend handwashing all Berry Fun Yarn in cool or tepid water with a pH neutral soap like Eucalan. Once we dye the yarn, we do wash every hank to assure the dye has both set and is easy for the customer to work with. We also recommend storing your yarn and finished products out of direct sunlight.

  - KitsLooking to make a fabulous winter hat with a beautiful faux fur pom pom? Or maybe a special project that has just the right amount of yarn needed for the project? If so, then these kits are for you!
  - Sock Sets + 50 gram SetsLove to make socks with matching heels, toes and cuffs? Or maybe you need 50 gram skeins for colorwork projects. These sets are perfect for you!
  - Mini SkeinsFor those who can’t decide on one color, or who are working on a multicolored or scrappy project, these smaller mini skeins are perfect. They come in either 10 or 20 gram sizes, as well as multiple bases.
  - FingeringFingering weight yarn is often used for baby items, socks, shawls, and other lightweight accessories and garments. It is approximately twice the weight of a lace yarn, and is typically knit using a US size 1-3 (2.25-3.25 mm) knitting needle or a size B-1 to E-3 (2.25-3.5 mm) crochet hook.
  - LaceA superfine yarn that is great for lace work. Great for projects that wish to evoke an ethereal or floaty feeling. Laceweight mohair or silk is also wonderful when held double with another yarn to create extra warmth and texture. Most commonly used with size US 000-US 1 (1.5-2.25 mm) knitting needles or a 1.4-2.25 mm crochet hook.
  - Sport/DKSport is slightly heavier in weight than fingering and DK stands for double knitting weight. This category of yarn is a great middle of the road weight, perfect for all projects from hats and mittens to baby items and even garments. Most commonly used with size US 5-7 (3.75-4.5 mm) knitting needles or a size 7 to I9 (4.5-5.5 mm) crochet hook.
  - Worsted/AranWorsted/Aran are the two thickest yarn bases that I currently carry. Both weights fall into the medium weight “4” category as given by the Yarn Council and are great for a multitude of warmer projects from hats to mittens to garments and blankets. Gauge would generally be 16-20 stitches over 4 inches with the use of US 7-9 needles or a crochet hook size I-K.
  - Discontinued!Looking for a deal? The yarn in this category is either a retired base or colorway. Still perfectly wonderful in its own way, but limited in quantity.
- Yarn Tools & Accessories No knitting project is complete without the perfect set of needles and the right stitch markers or progress keepers to keep things organized. In our online store you find our favorite, ChiaoGoo premium knitting and crochet tools. ChiaoGoo offers a complete line of bamboo/wood and stainless steel knitting needles and crochet hooks, as well as organizers to keep everything at your fingertips.

Grapes season has ended and we are now closed for the season. Thank you to everyone who came out to pick grapes. With your help we saw nearly 10,000 lbs of grapes leave our vineyard! We will see you in the spring of 2025 with strawberries.

Welcome!

Firefly Berries is a small, family-owned fruit farm located in Rochester, Minnesota. We specialize in prepicked strawberries, and both you pick & prepicked concord grapes. We also have our own naturally dyed yarn line, Berry Fun Yarns, dyed primarily with plants we grow on our farm. We are only open to the public during the months of September and October when we have fresh grapes available for customers to pick. If our June strawberry crop is plentiful enough, we will also offer you pick strawberries. From May through October you will find us most Saturdays from 7:30 am - 12 noon at the Rochester Farmers Market (located at the Olmsted County Fairgrounds) where we sell what is in season, be it strawberries, raspberries, blackberries, or concord grapes. And we always have naturally dyed yarn, raw honey, and jam with us as well! If you cannot make it to the farmers market, you can purchase our canned goods (for local pick up only) as well as our naturally dyed yarns (to be shipped anywhere) in our online shop. Click on the "shop" link at the top of this page to see our current offerings.

About Us

We are a small, family owned and run farm. We purchased the farm in 2010 and although we occasionally hire additional workers, the vast majority of labor is done by us and our four children.

Weeding

We do not spray any chemicals anywhere on our farm. All weeding is done by hand except for the help of the hydroweeder.

Pruning

In the beginning just the adults did the pruning, but the kids watched and learned. Today the kids are ages 11-20 and everyone helps with pruning.

Harvesting Strawberries

Our strawberries are harvested by us and sold as prepicked quarts and flats for our customers to enjoy. Strawberries can be purchased online for curbside pickup and at the Rochester Farmers Market.

Harvesting Concord Grapes

Concord grapes are available both as you pick and already picked flats. Check back in early September for more information on picking times and days.

Thank You

from our family to yours
