- Canned GoodsFirefly Berries offers many varieties of jam and jelly, as well as 100% Concord grape juice, all canned to last at least a year in your cupboard, or up to two weeks in your refrigerator once opened. At this time, these products are only available for local pick up.
- Fresh ProduceFrom strawberries to grapes to herbs, if you’re looking for fresh produce that we grow on our farm, this is your place to look. All fresh produce is only available for Saturday morning curbside pick up. We do not ship fresh produce.
- Berry Fun Yarns 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.
  - Advent 2025Inspired by the 1994 Disney movie, The Santa Clause, the 2025 Advent Countdown kit is full of lots of holiday spirit and color.
  - 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.
  - 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.
  - Sport/DKSport weight is slightly thicker than fingering and slightly thinner than DK. DK stands for double knitting weight. Both sport and DK are great middle of the road weights, perfect for all projects from hats and mittens to baby items and even garments. Sport and DK is 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.
  - MinisMini skeins are perfect for colorwork, scrappy projects, and so much more. Minis are dyed on both 20 and 50 gram skeins.
  - ClearanceLooking 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.
  - Kits and SetsLooking 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!
