20140418 7089 quarter-inch twill test

Until last night, I would have said that the 1/4" twill tape (of which I have several hundred feet that has been soda-washed and dyed a lovely turquoise) that I purchased in January was a bust.  The garlands that I made with it have worked pretty well but have been prone to foldovers. Last night, I decided to see if smaller looplets than I have been using would be less foldover prone with this lightweight twill.

My earlier twill garlands all had 5-7 inch looplets (where the size is the length of the looplet top-string). I decided to see if smaller looplets with the 1/4" twill would be less prone to foldovers. I have wanted a garland with smaller looplets for really windy days; so, I thought I'd give it a go with this particular twill. I quickly whipped up a twill garland with 3" top-string looplets. The bottoms are 6". It worked great. No foldovers. Lots and lots of 3 to 4 inch bubbles were produced.

This looplet size seems ideal for this particular twill. The design was optimized for speedy construction. The garlands' top and bottom are each a single length of the 1/4" twill. I used hot-melt glue and a mini glue-gun to join the bottom and top strings.

There is a 1-inch space between loops. For a 12-loop garland, I measured out 51 inches of twill. That provides a one-inch leader at either side of the top plus one-inch space between loops and a 3-inch top for the loops. For the bottom, I cut an 85-inch length of twill which provides one-inch for the space between each looplet and a six-inch section for the looplet opening.

Construction

The diagram below shows the basic design. In the diagram 'G' is the gap width. This is the space between looplets. 'Leader' is some extra fabric used to make a leader that you use to attach to your wand. For the top piece, the space between the gaps (G) is your looplet size. Let's call that T (for top). For the small looplet garland, I used T= 3". B is the space between gaps for the bottom part of the looplet. I like to have the looplet bottom be twice the length of the top. So, for the small-looplet garland, I use 6" for B.

Calculating the material

Here are the formulas for determining how much material you need to construct a garland with the basic design showed above.

L= leader length; G= Gap between loops; T= looplet top-string length; N = number of loops, B=bottom looplet length

Top length = 2L + ((N+1)*G) + NT Bottom length: = ((N+1)*G) + NB

Example

Here are the calculations for a garland with 12 3" looplets (whose bottoms are 6" long) and a 1" gap and a one inch of leader N = 12; G = 1"; L = 1"; T = 3"; B = 6"

Length of top piece = (2*1) + ((12+1) * 1) + 12*3 = 2 + 13 + 36 = 51"

Length of bottom piece = (13 * 1) + 12*6 = 13 + 72 = 85"
