Cross stitch projects use tapestry point needles.
Aida is the material used for Counted Cross stitch. The Aida number represents how many threads there are in an inch. So you can make 14 “x” stitches in one inch of size 14 count Aida. The higher the number, the smaller the holes are between the weave. So a size 11 count Aida would have bigger holes than a size 14 count Aida.
Most cross-stitchers use tapestry needles for their project. This if or two reasons.
A tapestry needle has a blunt point so it will not pierce the material threads, going effortlessly through the intended hole in the Aida material.
When putting a sharp needle through the project you might prick your finger on the hand under the hoop and cloth.
It is a personal preference. For reference, a size 24 Tapestry is similar in size to a size 6 Sharp or 7 Chenille.
