Happy New Year, Belated Merry Christmas and Soon to be Chinese New Year!! Missed out alot on this festivities and holidays. So to make up for it, here is some "Wisdom" and also reasons why my pattern scribbles always get messed up and missing...Yikes... Sorry.
Here is a demonstration on how to imagine out the potato body before even making it... Just for learning purpose and you will be undoing somepart along the way. Have patience and Confidence :D
See you can start from bottom or top, Lets say we start from bottom to top, 6mg, then follow on the inc in all (12), sc inc in all (18), 2sc inc in all (24), 3sc inc in all (30), 4sc inc in all(36), STOP. you reach the 36 max stitches. Place an "SC IN ALL" to just double check your stitches and increase the lenght of it or skip it to see how the curves takes place.
So now you go decrease but then again, you need 15 stitches next, so in between the 15 and 36, what can be divided with the same number that can divide both 36 and 15? Its hard to count even for me... but i guess. 30 obviously, as 15 can be divided with 3, and so as 36, so in between that 30 also can divide 3 (I just do 3x equation table and take the one i like between 36 and 15).
Okay now we know we need to go to 30 stitches first, remember the 6, 12, 18, 24, 30, 36 thingy above highlighted? (6 is actually the Magic ring which already have 6 stitches on). From 30 to 36 it was "4sc inc in all", so to reverse it, its "4sc, dec in all". That will reduce the number of stitches to 30.
Now you have 30 and want to go to 15, but 15 is not in 6 multiplications, its okay try the 5 multiplication table. 5, 10, 15, 20, 25, 30.... from 5mg, inc in all (10), sc inc in all (15), 2sc inc in all(20), 3sc inc in all (25), 4 sc inc in all(30). So you need to go from 15 to 30 but you have "sc inc in all (15), 2sc inc in all(20), 3sc inc in all (25), 4 sc inc in all(30" which is 4 rows in reverse replacing inc with dec. Depending on whether you want to keep that 4 rows by replacing it with decrease or taking the "4sc dec in all(30)" and trying the extra dec in it to reduce the number of rows, but to do an extra dec, minus 2 from the 4sc and you will get "2sc, dec, dec (6 used stitches)" in all also equal to "sc, dec in all" (3 used stitches). So "sc, dec in all" for 2 rows i think? then you have your 15 stitches
Keep in mind that the curve will force inwards when dec to the number of stitches it suppose to make. so directly going from 30 to 15 will stretch the yarn. Keeping the 4 rows is better and stay as close as "sc, inc/dec in all" instead of "dec in all", as "dec in all" will flatten and try to close the hole up.
Finish it up by using the 5 multiplications of 5mg, inc in all (10), sc inc in all (15), 2sc inc in all(20), 3sc inc in all (25), 4 sc inc in all(30) so that from 15 it repeats again to 30 and then back 0 to end off. ( Looking from top, the row of rings grow outward with increase and grow inward with decrease, so from 15 to 30, you increase then from 30 to 0 you decrease based on the technique above)
So this is how i roughly shape the dolls before making it. For the actual Potato, try using 25 or 27 stitches minimum for the diameter instead of 15 as 15 would make it look like number 8.
Any Questions please feel free to ask, as i will sure to reply but takes really long time sometimes. Depends on the situation actually.
Here is Basic Multiplications :
2mg, inc in all (4), sc inc in all (6), 2sc, inc in all (8), 3sc inc in all (10), 4sc inc in all (12)
3mg, inc in all (6), sc inc in all (9), 2sc, inc in all (12), 3sc inc in all (15), 4sc inc in all (18)
4mg, inc in all (8), sc inc in all (12), 2sc, inc in all (16), 3sc inc in all (20), 4sc inc in all (24)
5mg, inc in all (10), sc inc in all (15), 2sc inc in all(20), 3sc inc in all (25), 4 sc inc in all(30), 5sc inc in all (35)
6mg, inc in all (12), sc inc in all (18), 2sc inc in all (24), 3sc inc in all (30), 4sc inc in all(36)
7mg, inc in all (14), sc inc in all (21), 2sc, inc in all (28), 3sc inc in all (35), 4sc inc in all (42)
Okay Thats it, so to add extra inc or dec just take 2sc from the main and replace it with dec or inc. Have fun Playing :D
