I never have Monica *

I use the target stickers (the "snowman") that came with my Quattro and they are great. Or do you mean these particular stitckers? Sorry if I misunderstood.

Your link doesn't give a price, but I am sure regular adhesive dots that you can buy at walmart will accomplish the same thing and most likely a lot cheaper too! I recently received an email from one of the embroidery sites selling these as an alternative to fabric markers and my first thought was I can use, any dots from any store and save money. If you do decide to use these to line up your design for placement in the hoop dont forget to remove the dot before you start stitching
(trust me on this one) OOOOPS!

I just use the blue painters tape

I do not use them instead I use a pen that disapears of washes out, not playing games with stickers they would probaly stick to my fingers to much and annoy me and would end up a rolled up ball LOL

I use the stuff that comes on t-shirts etc that gives size and price. It has a sticky side and a smooth side. cut it into strips and mark horizontal and vertical and lay your plastic grid over to line up. just remove before you begin to stitch. It can be used several times before it looses it's sticky.

I use the snowman targets all the time..even better when printing out using Embird it prints the snowman so I don't have to use the stickies. I do love my Quattro!
