Rabbi Menashe Klein Zatzal in Mishna Halachos 13:3 in discussing shoes with a zipper concludes that it is best to close the zipper in the same order one would tie his shoes.
I would conclude from this that velcro would also be the same.
See this page on Tiferes Stam, which shows a diagram with instructions for both the double- and single-daled knots, as well as information about how the tefillin should fit. The instructions for tightening the double-daled knot are:
Say לשם קדושת תפילין, then
Pull the strap marked with the arrow down, making the head loop smaller
Close the loop you just ...
One does not tie a "permanent" knot on the tachrichim (burial clothes) in order to show that the death is not permanent. That is, the person will get up at techiyas hameisim (resurrection of the dead) after the mashiach comes. Additionally, the knots are this way so as not to hinder the dissolution of the tachrichim with the body. The chevra kadisha that I ...
The practice of tying a knot to find a lost object is found in wiccan practice , and may have originated in ancient Greek culture
Furthermore, even if these foreign practice somehow snuck into Jewish forklore, doing 'spells' , or 'charms' , or anything of the sort, is inconsistent with the Torah:
When you have come to the land the Lord, your G-d, is ...
According to this article:
Before the chuppah all the knots on the groom's garments are untied.
This symbolizes that at the moment of marriage all other bonds are
eliminated, except this intimate one made between the bride and groom.
Apparently, this may be a Hassidic custom? I haven't seen any weddings where I have seen this done. Then, again, I ...
Mois Navon of the Ptil Tekhelet Organization offers video tutorials via YouTube for tying the various methods of tzitzit with techelet.
For tying tzitzit without techelet, please see these videos:
Hope this helps. Please note that all of these videos come from Orthodox, non-Messianic sources.
There are two reasons to tie the left shoe first, either because the gemara in shabbos 61a says 'the same as tephilin, so too with shoes'. It is disputed there whether or not to do this at all, with many rishonim ignoring this practice, the Rambam for instance. But Rabbeinu Yona, brought in many achronim says a Yorei shomaim should do this, being that the ...
The book The 39 Avoth Melacha of Shabbath* on Page 32 has an illustration that specifically forbids this (as Rabbinic, IIRC a Torah prohibition).
It sources the statement to Kitzur Hilchos Shabbos 25, 2 and Shmiras Shabbos Kehilchasa 15, 50.
The single-Daled knot is made of a vertical and a horizontal strap, when looked at from the outside.
The horizontal strap is woven around the vertical strap.
The vertical strap goes straight down - but is S shaped. IOW it goes down, up again and then down again. But it's not twisted or tangled.
To adjust the straps, you move the vertical strap.
see this: double dalet (not the square) knot
If you are referring to the double knot below.
Quote from site: "There is a third, rarely seen, type of knot which is made from two ד knots – an inverted ד under a regular ד. This is most likely the true “double-ד” knot2. This double-ד knot is mentioned by some sources as having kabalistic origins, but many ...
You can always retie the knots but the result won't be the same as Nusach Ashkenaz tefilin.
Many years ago I purchased Nusach Ari tefilin, after being told that ktav Ari was accepted by both Ashkenazim (Litaim) and Hassidim. Once I learned hilchot tfilin in more depth I discovered that there were other important differences between Ari and Ashkenazi tefilin....
Toys that kids can play with in general are not Mukza but should not be used by adults unless they need to move the toys for the sake of the kids (Sh"t Iggerot Moshe 5:22:10, Sh"t Beer Moshe 6:24, Sh"t Yabia Omer 7:39 thanks chacham Nissan from Halachapedia)
There are 3 potential malachos to be aware of: building by making an ohel tefach - a roof with a 3....
Halachipedia citing O.C. 317:5, and other sources, says:
A bow-knot, slipknot, or a single-knot isn’t a true Kesher-bind and is permissible even if it does remain in place for a while. 
For example: a ribbon on a gift, a single bind on a shopping bag or
It is permitted to tie a slip knot or bow without a underlying knot even if ...
As @NoachmiFrankfurt mentioned above, and suggested I convert into an answer:
Here's a partial answer: The MMA madrich gives requires a double-dalet knot http://www.moreshesashkenaz.org/en/guide.
Furthermore, there are Sephardim, such as the London community, who also maintain this practice: https://sites.google.com/site/londonsephardiminhag/tephillin
Rav Shachter has said (and written in Nefesh HaRav) that Rav Soloveitchik consistently advised students to follow their father's minhagim, with two exceptions: (a) eating in the sukkah on shmini atzeret, and (b) the shape of the knot in the tefillin shel rosh, where he thought that the alternative view (i.e., not eating in the sukkah and the double dalet) ...
In the corner
SA OC 21, 1:
חוטי ציצית שנפסקו יכול לזרקן לאשפה מפני שהיא מצוה שאין בגופה קדושה אבל כל זמן שהם קבועים בטלית אסור להשתמש בהם כגון לקשור בהם שום דבר וכיוצא בזה משום בזוי מצוה.

This is an interesting question and is mentioned in Talmud (but I cannot remember the exact source).
You give "honour" to the right in which order you put the shoes on. This is partly derived from the order of the Temple service, and also we partly know from Jacob's blessing to Ephraim and Menashe that there is a special honour to the "right".
However we ...
See Shulchan Aruch OC 27, 10 and Magen Avraham sk 16:
The first question is if someone can argue that a knot is not Kasher at all. For we need clear instructions. In this regard, here is what is provided by Shulchan Aruch and Magen Avraham:
צָרִיךְ שֶׁיִּהְיֶה הַקֶּשֶׁר מֵאֲחוֹרֵי הָרֹאשׁ לְמַעְלָה בָּעֹרֶף. צָרִיךְ לְכַוֵּן ...
It is well known that the Rav (Soloveitchik) held everyone should follow their families minhagim and not pick up minhagim from him or elsewhere. However,he held that when it came to the minhag of not sitting in the sukka Shimni Atzertz and using the double daled for the shel rosh one should change their family minhag. This is recorded in Nefesh HaRav(Rav ...
If I am reading the Tosfos properly, it appears that it is a matter of actually tying and untying the knot every day rather than just settling it around ones head (as we do). The point of the Tosfos seems to be that one does not undo the knot and redo it the next day and one of the proofs is that it is forbidden to tie the knot of the tefillin, not just ...
I think the standard when putting t'filin on another person is to put it on a right-handed person's left arm and a left-handed person's right arm irrespective of the handedness of the one putting it on him. Since the order of tying shoes is derived from the arm on which one puts t'filin, I propose that it depends on the handedness of the one wearing the ...
Actually there are others who were concerned over the issue, which, as SethJ notes above, is referred to as notef al hakanaf, meaning it should hang down along the side, not from the bottom.
The Chazon Ish held that you should tie the first knot really snug so that it bunches up the fabric, and that way the tzitzit won't budge. You see a lot of avreichim (...
