Converting yarn weights

Knitting friends, I'm back after a rather lengthy absence, and have a question for you. I've found a pattern for a "kimono" sweater-jacket that I would like to make. However, I don't care for the colors available in the yarn called for (sport weight, doubled) and would like to know how to convert that to a single yarn... maybe a heavy-worsted, or ??? In the picture it didn't look bulky enough to be a bulky-weight yarn. Any help and/or suggestions would be greatly appreciated! Thank you.

If you have a favorite four-ply yarn, try making a gauge swatch with the needle size suggested. This should give you an idea as to whether you can convert. Keep in mind that colors have a lot to do with the thickness of the yarn used, so be certain to do your swatch in the yarn you plan to try to use. Good luck and Happy Knitting!!! Marian

Thanks, Marian. It simply hadn't occurred to me that something so simple could be the answer! How dense am I? Glad to know that you are still posting here -- I've missed all the regulars during my absence. I had learned so much from all of you before, and it's good to be back so I can learn more!

Don't forget that yardage is different for sport weight than for worsted weight. You will need to calculate what you need by figuring the total yardage for the pattern as given (and remember it called for double strand), then converting to your intended yarn so you know how many skeins to buy. Many yarn manufacturers give yardage per weight info on their web sites.

Hoo boy! Now I remember why I hated math in school! (big sigh)OK - so if it calls for a total of 1,400 yards (both strands) in original yarn, then would I need 1,400 yards of the substitute yarn? Or 700? Or ??? Now I'm really confused! But thanks for the reminder of that important factor.....

Whew! Many, many thanks for spelling it out for me so clearly! I just couldn't seem to get my mind wrapped around that concept. (I'm blaming it on the fact that I had another birthday last week and am now using an old brain!) Thank you all for taking the time to answer my question. I appreciate your responses.

If you are working with two strands of yarn at the same time, and the pattern calls for 1,400 yards of each color, then if you find a heavier weight yarn, you should be able to make it work with just 1,400 yards of the heavier weight yarn.

If your pattern had called for a total of 1,400 yards and you used the y arn doubled, then you would need about 700 yards of the heavier weight yarn.
