What do I need for felt slippers?

First, we start with the right wool selection. To felt your slippers made from felting wool as well as possible, you need pure virgin wool made from 100% natural fibres. In addition, the wool must not have a superwash finish, otherwise it will not felt in the washing machine.
All our felting yarns are OEKO-TEX® certified and therefore tested for harmful substances. The best basis for warming accessories.
For everyone who is a fan of plain-coloured yarns: our Gründl Filzwolle uni and Filzwolle Funky impress with their solid colours in every ball.

Felting wool in neon colours

Bright, radiant neon colours await you in the colour palette of Filzwolle Funky. A total of eight neon colours look unique on their own, and combinations of them are definitely eye-catching too. And we tested it: neon-coloured Filzwolle Funky also glows under black light. Perfect for bracelets or accessories that should shine in neon light.
More subtle shades such as pastels and earthy colours, together with bright patterns, belong to the harmonious colour family of Gründl Filzwolle uni. Wonderful to combine with both plain and patterned felting yarns, or used on its own as an elegant plain felted unique piece.

Felting wool with colour gradient

Next up are multi-coloured felting yarns from Gründl. We love our Filzwolle color and Filzwolle Spectra and their exciting colour sequences that come straight from the ball. Without colour changes and knotting, colourful felted unique pieces are created.
Harmonious colour gradients await you with the Gründl gradient yarn Filzwolle Spectra. A total of ten unique gradients recall a rainbow running through your felted knitted or crocheted piece. Believe us: with this yarn, you will want to keep knitting forever. Stitch by stitch and row by row, another shade appears and contributes to a harmonious work of art made from felting wool.
It continues just as colourfully: our Gründl Filzwolle color impresses with fourteen patterned colourways for colourful felting projects. Every ball brings an unmistakable colour composition. Combined with the plain-coloured counterpart Filzwolle uni, you can let your creativity run free and create individual felt projects that everyone will envy.

Knit-felting: knit felt slippers yourself

And then the big slipper felting adventure can begin with knitting needles, suitable felting wool, tennis balls and a washing machine. Yes, you heard correctly: felting is done at home in your own washing machine.
First step: make a gauge swatch. This gives you the best possible guarantee that your self-felted slippers will match your desired size after the felting process.
Then you can get started. The slippers are begun at the heel. Depending on your desired size, you start by casting on the required stitches and knitting a certain number of rows in stocking stitch. You can find the exact information in the respective instructions. Below you will find an example table for reading the size.

Let’s continue...

As soon as you have finished the heel, the stitches can be distributed evenly over four double-pointed needles. Now continue knitting in rounds, casting on two additional stitches at the front centre in the first round. From now on, knit round by round, following the information in the table. Then comes the toe. For this, knit the last two stitches of each needle together in every round and repeat this step until only two stitches remain on each needle. Pull these together with the working yarn and sew in the thread. Now your felt slippers can be finished. Close the back seam, meaning the cast-on edge, of the slippers as flat as possible with felting wool.
Then the felting can begin. Put your felt slippers into the washing machine together with three tennis balls. At 40°C in a coloured wash programme lasting around two hours, with a spin speed of 800 - 1000 rpm, the natural scales of the pure wool interlock. Make sure not to select a short wash or eco programme. We recommend using a little liquid detergent, as this has the advantage that no small grain-like residues can form. It is important that the detergent is free from optical brighteners and built-in fabric softening care. You should also avoid fabric softener.

Felting in the washing machine

As soon as the button on your washing machine is pressed, the felting process for your slippers begins. We recommend taking your felted unique pieces out of the machine as soon as possible after washing, as this prevents unattractive creases from forming.
Now it is time to bring your finished felted pieces into shape and let them dry. To achieve the best shape for your felted knitted or crocheted pieces, we recommend putting on your self-felted slippers. Slip into your still-damp felt slippers after the felting process, because while you wear them the shoes adapt to your feet. Now you can immediately tell which is the right and which is the left shoe. Then let your pieces dry thoroughly.

Benefits of felted slippers

Small mistakes or uneven stitches? Yesterday's news. After the felting process, uneven spots in your felt shoes disappear as if by magic. That is why felting projects are wonderfully suitable for all knitting and crochet beginners.
And that is not all: the stitches and rows of your felted slippers are so firmly connected that no runs can occur after felting. For long-lasting slippers that enchant you with their unique durability and unbeatable heat retention.

Decorating felt slippers

Yippee. As soon as you are holding your felted shoes in your hands, it is time for the final step: decorating your slippers. We love handicraft accessories of all kinds to give handmade felted unique pieces the finishing touch. Wooden buttons, glass beads or pompoms: depending on the colour of your felt slippers and the style you want to give your shoes, you are sure to find the perfect decorative element to complete them.
PS: do you already know our pompom maker? It lets you create even, voluminous pompoms in no time and use them to decorate your shoes.

Decorating felt house shoes

Embroidery also looks wonderful on felted shoes. We think this option is especially practical and clever for family slippers, because if every family member finds their initial on their shoe, there can be no mix-ups.
Of course, you can also create matching decorations from felting wool. Felted bows or felt buttons look wonderful and match your felt shoes perfectly.
Staying with accessories made from felting wool, another option is to use needle-felting to felt colourful shapes and colours onto your finished felted shoe afterwards. How about a heart? Or a monster face for children? Here, your imagination truly has no limits.
