Help 3d knit

Hi, im having trouble with my 3d. I wanna make a knit of this 2 forms i made from the partition of a bottle. The knit would look like the draw i made in the image. The blue form would be the upside of the bottle, while the red form, the downside. I would like to do this knit by anchoring the extremes of each form as i draw in the image, so in that way i could transform, modify the knit in 3d without separating the planes where the extremes of each form joint. I would appreciate if someone help me with this and im uploading the rhino and the grasshopper of my progress. Thanks. and have a nice day.
