I want to try my first closed wrap and am trying to figure out the amount of threads i need for which colors and to successfully close the wrap.
I have the visual wrap software which is good for visualizing the wrap but does not account for thread size or count as I would imagine some of you know.

Is there a calculation that people use to figure this out or do I just have to spend all the time on this, cut and restart if i fail miserably?

I will use either fuji A or D thread on an inshore blank with the butt end diameter of 11 and tip end diameter of 9.7
Pros and cons to either A or D?

Thanks in advance for any help.

Just keep wrapping until you have the wrap closed in. You won't "fail" miserably. You will have to pack a bit more towards the top end of the wrap and burnish and spread a bit more towards the butt end of the wrap. Some will use Taper Offset Spacing for more precision but honestly unless there is a very steep taper along your wrap length I've not found it necessary.

If you don't have it, I recommend Decorative Wraps by Billy Vivona. It goes into the details on how to calculate things - along with many other helpful details on doing a closed wrap. I look at VisualWrap and DecorativeWraps as going hand-in-hand

VisualWrap will give you the details you need for tapered spacing, which you should use for a closed wrap to help things close out evenly. Be VERY meticulous with your layout threads to the spacing and pack to the spacing marks.

As to calcul;ating the space needed for the close - Size A, and Maderia is about 4.1 threads per mm. Most doing closed decorative wraps are using A as it looks better, and with all the crosspoints in a closed wrap is going to allow you to pack it easier - in fact this is a benefit of Maderia threads - the silicone in the thread helps it slide a bit - but you MUST use mutliple coats of color preserver to seal the thread (and the silicone) so it does not affect your epoxy.

"Life's too short to fish a boring rod"

IF a customer wants a wrap and a closed wrap at that I look at the particular blank. On a shorter blank with lots of taper I will use a TOS layout. If the blank is something like a 11 or 12 foot surf rod I do not bother. The area in front of the seat and foregrip will have so little taper you can just manipulate the thread in there. Don't make things hard on yourself, its not rocket science.

What is a closed wrap?

A closed wrap is made by continuing to wrap threads until there is no underlying blank or under wrap showing in-between the main center pattern threads.

Worked off of he plan I had in visual wrap. Had o add a few to fully close bu not much. Happy with how it came out thanks for the help.
