Step 1
Make a table:
A | C |
B | D |
Step 2
Weigh your ball of yarn, taking Somen as an example: 1 bobbin of Somen weighs 100g. Write it down in the table at position D.
Step 3
Knit or crochet a piece in a surface area of your choice. We knitted a piece of exactly 10cmx10cm, which gives us a surface area of 100cm². Write the 100cm² at position A in the table.
Step 4
Weigh this piece. Our piece weighted 8g. Write this down in the table at position B.
Step 5
A 10cmx10cm=100cm² | B 8g |
C ? | D 100g |
Now you will calculate how many cm² you can crochet with 1 bobbin of 100g. Write the answer in the table at position C.
Calculation: A x D =….. / B = C
1. Multiply A with D. So in our case 100x100= 10.000
2. Divide the result at 1 with B. So in our case 10.000/8=1250
3. C is the result of 2. This is the surface area that you can knit or crochet out of 1 bobbin. In our case you can knit a surface area of 1250cm² out of 1 bobbin Somen.
4. Draw the square root from the number of C. Now you know how big the square is you can knit or crochet out of 1 bobbin. If you draw the square root from 1250cm² , the result will be the number 35. So you can knit a piece of 35cmx35cm out of 1 bobbin Somen.
If I want to knit a blanket of 91cmx120cm= surface area 10920cm2, how many bobbins of Somen do I need?
10920/1250= 8,7. So I will need 9 bobbins of Somen.
How much can you get out of 1 bobbin Hoooked yarn?
