Depend on the how many layers of material you are using and the part you are attaching, it might be better to use the smaller needle. For example, if you are trying to secure the snap assortment pack [ <a href="https://www.sparkfun.com/products/11347" rel="nofollow" >https://www.sparkfun.com/products/11347</a> ] to a piece of fabric, it would be better to use the smaller needle because of the diameter of the mounting holes.</p> BunnyProf urn:uuid:00d67c0a-faec-46c3-ed41-cc8098fb3735 2015-08-26T11:13:01-06:00 <p>Hi, What is the conventional size of these needles, please? Eg size 22?

Lilypad holes are at minimum 2.5mm diameter, more than twice the thickness of the thicker needle in this kit. I&rsquo;d use the smaller one unless you&rsquo;re working with stiff fabric, though.</p> Akatm7 urn:uuid:2d75d1ad-bff0-f7f9-be26-72a5b8c51206 2012-11-04T07:28:56-07:00 <p>How well would these go through Lilypad contacts?</p> AdamTolley urn:uuid:6a881b59-3e2b-084f-f4f5-a366217689a8 2011-03-29T16:52:27-06:00 <p>If not, you could try to square up the shaft a little with sand paper and wire-wrap them.</p> akcoder urn:uuid:341ff56f-4962-9d6c-315b-1795fa48bc98 2011-03-24T15:34:04-06:00 <p>If they are coated with a lacquer (which I doubt), that can be taken off with a lighter.
