Keep in mind that you will need more or less thread or yarn depending on the size of the hole. For example, a small hole may only require about 12” (30. 5cm) of thread or yarn, while a large hole may require 24” (61cm) to cover it. [1] X Research source Thread your needle with more thread or yarn than you think you will need. The size of the needle you use will depend on the item and type of yarn or thread you are using. Use a needle with a large enough eye to fit your thread through.

For example, you can use a standard light bulb as a guide for darning socks, or you can use the curve of a large bowl as a guide for darning a sweater or blanket. For some items, such as cloth napkins and tablecloths, using an embroidery hoop may be a better option.

Do not pull on the thread or yarn to tighten the stitches. Doing this will cause puckering. The goal is to use your curved object or the tension of the embroidery hoop as a guide to ensure that the darning will blend with the rest of the fabric.

Do not pull on the woven stitches either. This will cause puckering. Keep using your darning mushroom or embroidery hoop as a guide. Try to create the same weave tightness as the garment you are darning. For example, if you are darning a loose knit, then the stitches will need to be somewhat spaced out. If you are darning a tight knit, then the stitches will need to be tight.

If you decide to make a knot, make sure not to pull on the thread or you may end up with puckering. Also, make sure to tie the knot so that it is on the inside or wrong side of your item. Keep in mind that a knot may feel uncomfortable in the bottom of a pair of socks, so it is best to weave through a few extra times instead. This will be enough to hold the darning in place.

If your garment is a medium or bulky weight knit item, then you will need to use a darning needle or yarn needle with a large eye. If your garment is a lighter weight item, such as a jersey, linen, or fine knit, then you will need to use a needle with a smaller eye. You may also consider using a tapestry needle for an item with delicate fabric. A tapestry needle has a blunt tip, so it will be less likely to snag while you are darning it. [10] X Research source

Keep in mind that a darned hole will have a slightly different texture than the rest of your item, so it may still be noticeable even if you use the same color and size thread or yarn. However, the darned hole will stand out much less if you find a good thread or yarn match for your item.

Darning mushrooms are sometimes referred to as darning eggs. Darning mushrooms or eggs may come with or without a stand. Having a stand will make it possible for you to darn sitting or standing while your item rests on a table. [14] X Research source Remember that some projects, such as cloth napkins and table cloths, may be easier to darn if you use an embroidery hoop to hold your work in place. You can also find embroidery hoops of different sizes in craft supply stores. Evaluate your item before choosing a mushroom or an embroidery hoop.
